Synthetic Biology meets the real world

This website contains descriptions of interdisciplinary team-based projects that explore the intersection of electronics, 3D printing, sensor technology, low cost DIY instrumentation and biology - and policy workshops and outreach events. These projects aim to build open technologies and promote development of research skills and collaborations. They tap into existing open standards and a rich ecosystem of resources for microcontrollers, first established to simplify programming and physical computing for designers, artists and scientists. These resources provide a simple environment for biologists to learn programming and hardware skills, and develop real-world laboratory tools. Further, the Biomaker projects provide a direct route for physical scientists and engineers to get hands-on experience with biological systems.

Students from all Sensor CDT cohorts teamed up with students and staff from the Cambridge Centre for Smart Infrastructure and Construction to find potential sensor solutions for a variety of challenges and questions in civil engineering and the built environment.

The discussion focused around the detection of cracks and corrosion in steel reinforced concrete, the effects of salt and air pollution on masonry structures and drain blockages.

Together the students developed potential solutions and road maps for future research with the aim to initiate new collaborative networks, linking Cambridge University with other national and international centres of excellence in the field as well as with industry.

CDT students, Oliver Bonner and Josie Hughes, from the first cohort were interviewed recently on Cambridge TV about the Sensor Team Challenge on assisted living technology. The project was carried out in the final term of the MRes year at the Sensor CDT and involved the entire cohort working together as a group.

Watch the interview to find out more about the project and to hear why the technology developed has a particular relevance to a society with an ageing population.

The outcome of this research was recently published in the Royal Society's Interface Focus journal. Full coverage of the story can be found on the University of Cambridge website.

MedImmune is supporting the Sensor CDT as part of its Beacon project

Researchers from MedImmune and the Department of Chemical Engineering and Biotechnology are collaborating on a number of projects in the areas of bio-engineering, -processing and -pharmaceuticals.

This Beacon Project collaboration is part of the pharmaceutical cluster in Cambridge, addressing fundamental questions and challenges in this area.

Research students from the Sensor CDT are part of this collaboration, working on the detection of amyloid proteins and high resolution / high throughput imaging to understand spores and viruses.

We are recruiting for a fully funded 1+3 years MRes + PhD studentship, in collaboration with MedImmune, starting in October 2016. 

For more information please have a look at the project details.

Please note that this studentship is only open to UK and EU nationals.

The deadline for applications is Friday, 13 May 2016.

The first cohort of ten Sensor CDT students has successfully completed the MRes. Over the last eleven months the students attended a set of bespoke and in-depth lectures, received training on numerous advanced equipment across the University and carried out three projects of increasing complexity.

Their final project on a sensor suite which will help elderly people living a more independent life was a three months team effort. It was supported by mentors from the health care industry and some of the CDT's core industrial partners and supervisors. The results of the project, which already have received a lot of positive comments, will be presented at the Sensors Day.

The students are now embarking on their individual PhD projects in the Departments of Engineering, Chemical Engineering, Materials Science, Physics and Biochemistry. Topics include adaptive tactile sensing for robotics, measuring protein aggregation in primary containers for the pharmaceutical industry, bore well monitoring in oil and gas installations, ultrahigh throughout screening using micro droplets and advanced image processing for optical sensing.

In the run-up to the the imminent arrival of the first student cohort in a month's time, the Sensor CDT starts in style with a drinks reception and dinner at Trinity College.

This was a great opportunity for CDT supervisors, members of the industrial consortium and the CDT management and steering teams to meet, mingle and exchange ideas. The academic and industrial partners expressed real interest in contributing to the Sensor CDT and engaging with the programme.  More than 40 members attended the event.

Clemens Kaminski, the CDT director, gave a brief overview of the aims of the Sensor CDT and an update on the organisational progress and student numbers.

Many sensor related projects, research and collaborations were discussed over an excellent dinner in the Allhusen Room with its Leslie MacDonnald ("Max") Gill wind dial from 1926 on one of the walls - an example of an early "remote sensor".

Sensor CDT student Chris Valentine was awarded the Leete Premium award for the research he will be carrying out as part of his PhD studies.

The Leete Award is given annually by the Engineer’s Trust toy a 1^st year PhD student based at the Institute of Manufacturing (IfM), which is part of the Department of Engineering, Cambridge University. The award is the legacy of Dr. David Leete and has the stated intention to encourage manufacturing research to be undertaken by students.

For his PhD studies, Chris will be developing carbon nanotube based electrochemical sensors under the supervision of Dr. Michael De Volder (IfM) and Dr. Adrian Fisher (Chemical Engineering and Biotechnology). Feedback on Chris’ project stated that “The proposal described a credible fusing of established technologies as the starting point of the manufacture of much improved low cost sensors on-a-chip for gases, with prospects of advancing the products and their manufacture during the project.”.

Chris commenced the work in October 2016 and is looking forward to the next 3 years of exciting study.

Congratulations!

The international pharmaceutical company MedImmune has joined the consortium of industrial partners of the Sensor CDT. With its major R&D hub based in Cambridge, MedImmune has already strong links with individual researchers from Cambridge University and the Sensor CDT. Over the coming years MedImmune will support up to two PhD studentships per year in sensor areas related to pharmaceutical research. Students will be able to join the Sensor CDT with the agreement to pursue their PhD on a MedImmune project after completing their MRes year.

The 2016-17 MRes mini-research projects are drawing to a close. Last Wednesday, oral presentations filled a whole morning and the afternoon’s poster session saw the students engaging with the research community at the Department of Chemical Engineering & Biotechnology.

This year the interdisciplinary projects crossed the Departments of Engineering, Chemical Engineering & Biotechnology, Physics, Chemistry, Biochemistry, Materials Science and Geography, and the diversity of the field of “sensor” applications and technology is reflected in the choice of projects.

Examples of projects:

• Therapeutic Antibody Protein Folding
• Surface modification of Metal-Organic Frameworks
• Detection and characterisation of amyloid protein strains using H-D exchange mass spec
• Developing Cost-efficient Spectrometers for Real-time Biomedical Sensing
• Use Förster resonance energy transfer to enhance the photophysical properties of an existing photo-modulatable fluorescent
• High throughput imaging of amyloid fibril elongation and interactions using microfluidics
• Dynamics of mechanotransduction in single motile cells
• Lasers, rubidium and ultra-low magnetic fields: reducing the response time of an alkali-vapor magnetometer for ultra-low-field magnetic resonance
• Development of a prototype sensing system to detect the frequency and magnitude of turbidity currents in Adventfjorden, Spitsbergen – a feasibility study
• Modelling nonlinear behaviour in superconducting microresonators used in sensing applications in astronomy space science and quantum technologies
• Novel 3-D Printed Platform Approach for Gas Sensing Development
• Time of flight X-ray imaging

Josephine Hughes, an MRes student in the first cohort of the Sensor CDT has just published the results from her 8 week Mini Project entitled "Development of wireless sensor network using Bluetooth Low Energy for construction noise monitoring" in the International Journal on Smart Sensing and Intelligent Systems.

The paper focuses on noise detection and monitoring around the construction site of the London Bridge Station redevelopment and compares the performance and cost of different network technologies. The Bluetooth Low Energy (BLE) network was capable of identifying and locating vehicle noise around the construction site. The low cost of the system would allow to deploy a large number of sensor nodes around a construction site to monitor noise with great spatial resolution. Other types of sensors, e.g. temperature and humidity could be easily added to the network.

Josie has an Engineering degree from Cambridge University, where she specialised in Electrical and Information Engineering and gained particular experience in low cost open access technology during her final year project.

The new building for the Department of Chemical Engineering and Biotechnology, which is providing the hub for the CDT in Sensor Technologies and

Applications, is being built on the University's West Cambridge Site. This new building will bring the Sensor CDT  in close proximity to the activities of most of the other CDTs awarded to the University of Cambridge. Situated near the Cavendish Physics Laboratory, the Computer Laboratory, the Nanoscience Centre, Electrical Engineering and the Institute for Manufacturing the building will feature state of the art laboratory and teaching space and dedicated facilities to host the Sensor CDT cohort.  We are delighted to see the progress with the building which is on plan to be ready for the 2nd cohort of students to enter the CDT in 2015.  Have a look at the  video of the top out ceremony.

The University of Cambridge will receive £18 million in funding to ensure that the UK’s infrastructure is resilient and responsive to environmental and economic impacts. The funding will be used to support  research in the application of advanced sensor technologies to the monitoring  of the UK’s existing and future infrastructure, in order to protect and maintain it.

The funding is part of the wider UK Collaboration for Research in Infrastructure & Cities (UKCRIC), which is a £138 million capital investment that will be centred around the Olympic Park in Stratford and will include 13 university partners from across the UK.

The Cambridge funding will be used to build a National Research Facility for Infrastructure Sensing on the West Cambridge site, which will build upon the expertise of the University’s Centre for Smart Infrastructure and Construction (CSIC).  The new building will be an interdisciplinary centre for sensors and instrumentation for infrastructure monitoring and assessment, spanning scales from an individual asset, such as a tunnel, building or bridge, to a complex system such as a railway or a city district. More advanced sensors and appropriate data analysis will ensure better product quality, enhanced construction safety, and smarter asset management.

We hope to set up an exciting collaboration between this new centre and the Sensor CDT.

A prototype sensor for monitoring elderly people in their own home has been presented at the 2015 Open Technology Week which runs from 26-30 July at a number of venues across Cambridge.

 MRes student Tiesheng Wang presented the Sensor Box to an audience of enthusiastic engineers and scientist from academia and industry in the Department of Engineering. The Sensor Box contains sensors to monitor temperature, light level, movement and noise inside a person's home and sends the data to a server for further processing. E.g. if an elderly person normally gets up at 7am in the morning the light levels will go up. If this event is missing a smart algorithm will trigger an alarm and alert carers, family or friends.

The sensor is developed using open source hardware such as mbed or Particle board processors. The technological challenges are to reduce power consumption while ensuring a reliable connection to the server. The students use lab spaces across the University, e.g. Engineering shown on the right.

Josie Hughes, a Sensor CDT student in the first cohort, has been involved in organising the RoboCup Junior competition for some time. In 2015 she went to Hefei in China to help running the event.

RoboCup Junior encourages young people between 10 and 19 years of age to learn coding and engineering. Josie is actively encouraging students from Suffolk in the east of England to get involved. Her work has enabled students to take part in national and international robot competitions.

Her hard work behind the scenes has been recognised with the "Unsung Hero Award" as part of the Suffolk Raising the Bar Awards in June 2016.

Welcome to Fernando da Cruz Vasconcellos and Tanya Hutter

We would like to welcome the new senior teaching fellows, Dr. Fernando da Cruz Vasconcellos and Dr. Tanya Hutter, both who join us as Senior Teaching Fellows of the EPSRC Centre for Doctoral Training in Sensor Technologies and Applications (Sensor CDT). Fernando and Tanya will be helping with the course development, organising the student projects and mentoring.

          Fernando is a post-doctoral researcher from the Department of Chemical Engineering and Biotechnology here at the University of Cambridge where he works on Sensors for Healthcare Applications. He says, "I’m very excited to be part of the Sensor CDT and I'm looking forward to significantly contribute to the Sensor CDT through teaching, research and collaboration across the University, particularly in my areas of expertise of soft biological systems, functional materials and sensors."

     Fernando obtained a B.Sc. degree in Chemical Engineering from the University of California-Santa Barbara (UCSB) in 2000. From the State University of Campinas (UNICAMP), he received a M.Sc. (2007) and a Ph.D. degree, in a joint program with MIT, (2011) in Chemical Engineering. He served as Professor in the Department of Production Engineering of FACAMP, Campinas, São Paulo (2011-2012). Fernando has professional experience in the design, management and execution of engineering projects in multinational companies. He has broad international research and industry experience in the chemical engineering and biotechnology sectors, and he has been part of the founding team of two technology start-up companies in Brazil. Since 2013, Fernando has been a post-doctoral researcher and invited lecturer at the Department of Chemical Engineering and Biotechnology here at the University of Cambridge.  

     Tanya Hutter obtained a B.Sc. degree in Chemical Engineering from the Ben-Gurion University in 2007. She received a M.Sc. in Materials Science and Engineering from Tel-Aviv University in 2009. In 2013, she obtained a Ph.D. in Physical Chemistry from Trinity College and the Department of Chemistry, University of Cambridge. Between 2013 and 2014, she held a University of Cambridge-Wellcome Trust Senior Internship for Interdisciplinary Research. Tanya has experience in the theoretical and experimental design and development of various sensing platforms. She has been involved with CamBridgeSens since 2009, when she was a 1st year PhD student in Cambridge. Her team won the CamBridgeSens Sensor Competition to develop an integrated optical waveguide sensor. Tanya is also a co-founder of a chemical sensor startup in Cambridge.

     She says, "I have been involved in sensor research for several years now, and the multidisciplinary nature of this area makes it difficult to be placed in a single Department. I hope the Sensor CDT will bridge those gaps across various Departments and enable truly interdisciplinary research. I am very excited to see the CamBridgeSens network grow into the Sensor CDT programme, and I am thrilled to be part of the team."

The Sensor CDT took part in the annual Cambridge Science Festival.

A busy weekend in March 2016 saw around 2000 visitors coming to the Plant and Life Sciences Marquee where staff and students from the Sensor CDT demonstrated their prototype pulse oximeter. The general public, from school children to retired engineers, got an insight into how a sensor works, that is used routinely in clinical environments and in popular fitness monitoring devices.

The Sensor CDT exhibit was part of the Department of Chemical Engineering and Biotechnology stand, which showcased the wide range of life science research carried out within the department, from spores to nanoparticles, advanced microscopy and health care devices.

Watch the video below to see some of the highlights from the Science Festival:

A student team from the 2016 MRes cohort presented their pulse oximeter which they built during their Guided Sensor Project in December.

Carolina Orozco, Elise Siouve, Francesco Tonolini and Sammy Mahdi presented their Arduino based pulse oximeter to the general public in the Life Sciences Marquee on the first Saturday of the 2017 Science Festival.

Children were fascinated by a pulsing heart appearing on the computer screen as they put their fingers on an LED and the reflected light was detected with a photodiode.

Adults were interested to learn how the setup worked and surprised about how easy it seems to build a sensor that can measure pulse rate, blood oxygen level and temperature with a few electronics parts and an Arduino microcontroller.

As Carolina, Elise, Francesco and Sammy can testify, designing and building a sensor is not as easy as one might think.

Oliver Vanderpoorten, currently in his first year of PhD, demonstrated different microscopy techniques, including a lens-free setup to look at living mirco organisms in water droplets and an inverted microscope to study brain cells.

The second student cohort at the Sensor CDT featured in a recent article in the Department of Chemical Engineering and Biotechnology’s newsletter, CEB Focus (Issue 18, May 2016). Written by our graduate student, Dimitrios Simatos, the piece highlights the diverse range of sensor related mini-research projects undertaken by the CDT students during the MRes year.  

Each mini-project bridges across two University departments, providing the students with an exclusive insight into the work being carried out in the research laboratories in Cambridge, before deciding on a path for their own PhD projects.

Read the full article here.

The successful proposal has been brought together by teams from Physical Chemistry at the University of Cambridge and Engineering at the University of Exeter.

They were awarded £15,000 to investigate chemical sensing based on phase-change IR metamaterials devices. This project will run from June 2018 to September 2018 and will be an excellent opportunity to collaborate with colleagues from the University of Exeter and other EPSRC CDTs.

Sensor CDT student, Tiesheng Wang (王铁胜), found a simple way to transform metal-organic frameworks (MOFs) to carbon-base structures with ordered multilevel hierarchy, termed as “nano-diatom” (named for the morphological similarities with the naturally existing diatomaceous species). The metamorphosis is enabled by adding salts (metal-containing compounds) into the MOF followed by a high-temperature carbonisation process.

Tiesheng is a PhD candidate supervised by Dr Stoyan Smoukov and Dr R Vasant Kumar, and working closely with Professor Anthony Cheetham. Together with Dr Hyun-Kyung Kim, they have demonstrated one of the nano-diatoms as a superior carbon-based anode material for fast-charging lithium-ion battery. They published their work in JACS (Journal of the American Chemical Society) recently: http://doi.org/10.1021/jacs.8b02411

In the paper, Tiesheng and his collaborators from University of Cambridge, Queen Mary University of London and Max Planck Institute for Solid State Research proved that the transformation can be controlled by the initial chemical composition (i.e. MOF and metal-containing compound used). They also realized that the discovery can be applied as a working strategy for functionalizing the carbon not only for energy storage but also for catalysis and chemical sensing. Tiesheng, Stoyan and Hyun-Kyung have filed a relevant patent.

Since there are thousands of MOF and metal-containing compounds available, the discovery and its following work on understanding the formation mechanisms will enable the design of future carbon-based functional materials. The work is highlighted in the following press release:

Tiesheng Wang, a final year PhD student of the Sensor CDT, has developed a new flexible polymer material which moves electrical energy storage to new heights.

He weaved together a conducting polymer with an ion-storage polymer to form a new supercapacitor material with higher charge density than conventional polymer materials. In addition the material is flexible, allowing it to be incorporated into wearable sensors.

Tiesheng presented this work at the 255^th National Meeting & Exposition of the American Chemistry Society (ACS) in New Orleans in March 2018. Read the full ACS press release here.

His ground breaking research captured the scientific audience at a press conference held at the meeting.

Tiesheng Wang from the EPSRC sensor CDT is one of the award winners. https://www.csar.org.uk/student-awards/2018/tiesheng-wang/ 

His work on functional materials with interpenetrating structures was also recently featured in the recent American Chemical Society National Conference in New Orleans as both press release (https://www.acs.org/content/acs/en/pressroom/newsreleases/2018/march/candy-cane-polymer-weave-could-power-future-functional-fabrics-and-devices.html ) and press conference interview (https://www.youtube.com/watch?v=Goqth6IYyF4&feature=share). 

The awards were presented at a ceremony earlier this week, which was jointly hosted by Professor Stephen Toope, the Vice-Chancellor of the University of Cambridge, Professor Andrew Neely, Pro-Vice-Chancellor for Enterprise and Business Relations at the University of Cambridge and Professor Sir Mike Gregory, President of CSAR.

Farah Alimagham and Bogdan Spiridon, both from Sensor CDT 2015 cohort, took part in the Creativity Sandpit at Easthamstead Park. 

The main activities focused on "creating a solution to an industry problem".  The Greater London Authority, the Post Office and ARUP were the industry stakeholders.

Both Sensor CDT students prized the experience highly. Farah found it extremely engaging experience, working together with industry representatives and other PhD students to come up with feasible solutions to real-world challenges mainly involving managing and making sense of data and information.  Bogdan highlighted the opportunity to work together with people of varied backgrounds (high-performance computing, urban science and sensors) around real-world challenges. It was an excellent opportunity to network as well.

The first cohort at the Sensor CDT has just published the results from the Sensor Team Challenge - a 12-week project carried out during the MRes year. The research article, “Development of an open technology sensor suite for assisted living: a student-led research project”, features in the theme issue “Sensors in technology and nature” in the Royal Society’s Interface Focus journal.

With rapidly ageing populations placing increasing pressure on health services in the UK and many other countries, there is increasing demand for assisted living technologies to enable older people to live independently and safely in their own homes for longer.

But as team member Oliver Bonner, an electronics engineer, explains: “Existing monitoring devices are often too bulky, only perform one function and can’t be integrated because manufacturers don’t want their products used alongside those of rival brands. What we’ve done is develop an open platform so that anyone who invents an ingenious assistive device can bring that into the system and enhance what it can do for older people.”

The interdisciplinary team – comprising engineers, chemists, biochemists, materials scientists and physicists – designed and incorporated five assistive devices into their sensor suite: a door sensor, power monitor, fall detector, general in-house sensor unit, and an on-person location-aware communications device. The group improved on existing devices, in part, by taking advantage of recent developments in 3D printing, printed circuit board production and electronics prototyping.

Josephine Hughes, who studied engineering as an undergraduate at Cambridge and is now pursuing a PhD in robotics, said: “We’ve created a non-intrusive safety net that can be used to help older people live independently in their own homes for as long as possible while also connecting them with their friends and family. We had to ensure that older people would accept the system.”

To protect the privacy of older people, the in-house system uses motion and audio detectors to establish presence but no cameras or sound recording devices. Towards the end of the project, the team installed their sensor suite in the home of team member, Philip Mair, a biochemist. With kind permission from Mair’s flatmates, the group tested the system for two weeks and, to their relief, discovered that it was fully operational.

Extensive further testing would be required before the system could be commercialised but it has already generated expressions of interest from potential investors and manufacturers.

Many congratulations to our 2015 Sensor Champions, Josephine Hughes and Philip Mair.  Both students produced stellar work for both the practical and research components of the programme in their MRes year and fully embraced the interdisciplinary nature of the Sensor CDT course. 

Josie and Philip demonstrated a strong aptitude to learning new skills outside of their respective areas of expertise.  Philip, coming from a background in biology, used his skills and interests to venture into Machine Learning and soldering surface mount electronic components.  Josie shared her engineering undergraduate knowledge with the group when it came to programme Arduino micro controllers and designing electronic circuits.

Having immersed themselves in the theoretical and practical sensor-related aspects of engineering, physics, biology and chemistry, they are entering the start of their PhD research with an excellent grounding in the field of Sensor Technologies and Applications.

Josie is now conducting her PhD research in the Machine Intelligence Research Group, headed by Dr. Fumiya Iida, Department of Engineering, on the subject of Adaptive tactile sensing for robotics based on thermoplastics.

Philip is undertaking his PhD research in the Hollfelder Group, Department of Biochemistry.   His research is focused on the Ultrahigh throughput screening of metagenomic libraries. 

The second cohort of Sensor CDT students has been set the challenge of developing a 3D Optical Projection Tomography (OPT) system to image biological samples.

This 15 week project is interdisciplinary in nature and will draw on the collective, broad knowledge base of the student cohort whose backgrounds cover the natural sciences and engineering disciplines. Together they will design and implement a research standard OPT system to address scientific questions in the areas of biology, physiology and medicine.

The students will be supported by a diverse group of mentors from industry and academia, who will provide practical guidance on technical issues and project management. But ultimately the direction and realisation of the project will be in the hands of the students.

Low-cost, fast and reliable virus and chemical detection

The third student cohort has started its team challenge on cell-free molecular diagnostics tests for chemical or biological sensor applications.

In response to a growing need for enhanced capabilities in medical and environmental diagnostics the students' task is to develop low-cost open-source sensors to detect virus structures or polluting chemicals, such as arsenic, in an easy to use and rapid way.

Three months and twelve students

During this three months project the twelve students will use their engineering, physics, biology and chemistry skills as well as developing their project and people management skills.

Potential technology

The sensors will use synthetic biology to engineer safe cell-free gene networks which can detect specific analytes and produce outputs such as a colour change.

Several sensor platforms are possible, inlcuding paper based microfluidics. A key challenge will be the design of quantitative sensors. Here the student cohort will need to combine its know-how across the physical and biological sciences.

Scientific support and impact

The team challenge will run until middle of August, with plenty of opportunity for the students to interact with experts in the field from academia and industry as well as with students from the previous Sensor CDT cohorts working on relevant PhD projects and a group of undergraduate engineering students. Key guidance and advise will be provided by OpenDiagnostics, a student-led team which has carried out some pioneering work in this area.

At the kick-off workshop the Sensor CDT students collectively brainstormed a variety of possible avenues to approach this challenge.

Previous team challenges on assisted living for the elderly and a 3d optical imaging system have been highly successful.

Read more here.

The first cohort of Sensor CDT students is just starting its Sensor Team Challenge on Assisted living for the elderly. The students will develop a network of sensors helping to assist people in their homes to live a more independent life. After receiving a short briefing document the students will shape and manage the project mainly by themselves. External technical advisors and mentors will support the students with practical expertise and transferable skills, such as programme management.

The Sensor Team Challenge is the last of a series of projects carried out by the Sensor CDT students during the MRes phase. It brings together all ten students in the cohort to collectively work on a cross-disciplinary project which is of general interest to research and industry.

Students from the Sensor CDT and the Molecular Analytical Science CDT met at the Marston Vale Forest Centre about half way between Cambridge and Warwick for a packed day of academic and fun activities.

Problem solving - idea pitching

Mixed teams of students from the Sensor CDT and the Molecular Analytical Science CDT combined their diverse research experiences and skills to propose new products or solutions which could overcome a scientific or technical challenge in one of the team members' PhD project.

Ideas from the students ranged from capacitive sensors to detect crystallization and clogging in pipes to using scanning probe microscopy and NMR to investigate the shapes of active sites in antibodies.

It was impressive to see the students go from explaining their research to one another at the start  to forming efficient teams and presenting a new product in one day. During this exercise the students made excellent use of their knowledge in different science and engineering backgrounds and research areas.

Alongside the exercise students soaked up ideas to advance their individual projects.

Team building

The away day helped to create an expanded network of young scientists from both CDTs, which have complementary and partially overlapping themes: molecular analytical science is not possible without sensors while the develop of new sensors often relies on an understanding at the molecular level.

To develop their leadership and problem solving skills the student teams took part in team building challenges, including building a sculpture using a limited set of information and guiding blindfolded colleagues to erect a tent.

The day has allowed the students to connect across CDTs and cohorts and everybody is looking forward to future events between the Sensor CDT and the Molecular Analytical Science CDT.

More images from the day

The Sensors Day conference will bring together researchers from Cambridge, other international universities and industry to showcase exciting advances in sensor technologies and applications and related disciplines, including robotics and microfluidics.

Confirmed speakers include Prof Jeremy Baumberg, Cambridge, Luke Lee, Berkeley and Andrew de Mello, ETHZ.

This one day conference will be held on

Friday 16 October 2015
at
Murray Edwards College
Cambridge

The first cohort of Sensor CDT students will present and demonstrate their impressive intelligent sensor network for assisted living, which they developed during their three months Sensor Team Challenge.

Further information, including the full list of speakers will be announced shortly.

The second Sensors Day conference took place at Churchill College in Cambridge on 14 October 2016. Hosted by the Sensor CDT, the event brought an eclectic mix of talks to a broad audience from academia and industry. From sensing in the extreme environment of Erebus volcano to the bioimaging of an embryo, the day celebrated the breadth and diversity of sensor research, applications and technologies. 

The Sensor CDT students presented the Team Challenge on 3D Optical Projection Tomography. This was a 12-week project carried out in the MRes year at the CDT. Delegates were able to see the system developed to image biological samples during the intervals.

The poster session also captured the wealth of exciting research emerging from the sensor field. Poster presenters came from within the University of Cambridge, Centres for Doctoral Training (CDTs), and UK and European establishments. Among the contributors were the Sensor CDT students from the first cohort who are now entering the second year of the PhD phase.

The Best Poster prize was awarded to Lisa-Maria Needham for her poster entitled: “FRET-enhanced photo-modulatable fluorophore for improved super-resolution microscopy and single-molecule tracking studies”, and second place went to Jana Weber, “Predicting polymer chain growth Raman vibrations”.

Sensors Day 2016 was sponsored by Hamamatsu, NPL, the Royal Society Publishing and Andor. 

Sensors Day 2017 will take place on Friday, 13 October 2017.

The third Sensors Day conference took place at Robinson College in Cambridge on 20 October 2017.

As always, this conference brought together speakers from a range of sensing disciplines (see full programme here). Allard Mosk, Marina Kuimova, Tuomas Knowles and Ljiljana Fruk presented captivating talks on

• optical spectroscopy at the nanoscale to further the understanding of 3D materials
• the use of molecular rotors to image viscosity inside lipid layers, cells and aerosols
• employing microfluidics and sensors to understand protein misfolding
• using bio-nano composite materials for drug delivery, sensors

Robotics and the "internet of everything" were covered in two fascinating talks by Hatice Gunes and Ozgur Akan.

Julie MacPherson's work on diamond electrodes for electrochemical measurements lead seamlessly into the Team Challenge presentation of the Sensor CDT students. They had developed a quantitative arsenic sensor based on cell-free biology and an electrochemical readout.

The British Antarctic Survey presented a sweeping overview of sensor technology employed in harsh environments to monitor environmental changes.

Sensors Day 2017 was sponsored by Cambridge University Press, Department of Chemical Engineering and Biotechnology, Zimmer & Peacock, NPL, OpenIO Labs, Royal Society and Alphasense.

Undergraduate engineering students at Murray Edwards College enjoyed an afternoon at the end of term diving into programming Arduino microcontrollers and using their electronics skills to build a sound level meter and temperature sensor.

The event brought together 17 female Murray Edwards College undergraduate engineers from all four years of the Cambridge engineering degree. Thomas Quinn, a  3rd year undergraduate student at Loughborough University and Josie Hughes, a 1st year Sensor CDT student and supervisors for electrical engineering, delivered a course packed with fun and serious engineering. At the end of the afternoon the students were able to monitor and log their room temperature with an Arduino and left inspired to further explore the capabilities of microcontrollers.

The students only needed to bring their laptops and could keep their Arduinos after the event. Multicolour LED lights indicating sound level (left).

Visiting Professorial Fellow Denise Morrey and Oliver Hadeler, Director of Studies in Engineering at Murray Edwards College and Programme Manager of the Sensor CDT agreed that a basic knowledge of programming is an essential part of an engineer's education. Together with Alice Cicirello, Bye-Fellow at Murray Edwards College and Research Scientist at Schlumberger Research, they devised a course which was educational, practical and fun.

The event was supported by Murray Edwards College, Oliver Hadeler and Lee Smith, ARM Fellow.

Completed: Sensor Team Challenge on Optical Projection Tomography

The second cohort of Sensor CDT students has finished their 15 week Sensor Team Challenge. This project is a major part of the MRes course, requiring team work, technical and personal skills and focus. It gives the students a glimpse of a real research environment and prepares them for their PhD project.

The brief

The brief was to build an open source optical projection tomography (OPT) setup for less than £5000. OPT allows to image transparent (biological) samples approximately the size of a sugar cube in 3D with a resolution of a few micrometers. A commercial system has been available a few years ago from Bioptonics and an open source setup has subsequently been published. Both system, however, are substantially more expensive than the one designed in this Team Challenge.

Results

The setup was designed using an open source approach and avoiding proprietary hardware or software. After fully characterising their optical projection tomography setup the students were able to take high resolution images of transparent and fluorescent biological samples, such as C. elegans and organoids.

Future work

The students will present their work at the Sensors Day 2016 conference and then publish their results in the scientific literature. Design information will be published enabling interested researcher to build their own system.

A new cohort of 15 Sensor CDT students from the UK, EU and overseas has just started their MRes part of the CDT programme. They all have a common interest in sensing and will contribute their experiences and knowledge from a diverse background of undergraduate degrees in

• physics,
• bioengineering,
• computer science,
• biochemistry,
• electrical engineering,
• nano technology,
• neuroscience.

While the majority of the new students still have a few months to decide on their PhD project, some students are already working towards their projects with our industrial partners, e.g. MedImmune, Cambridge Display Technology and Alphasense.

It will be an exciting time ahead for them, as they learn about different aspects of sensing, trying out new ways of research and finding out what they enjoy most in the area of sensing.

The theme of the issue is "Sensors in Nature and Technology" and gives a fascinating overview of how sensors in nature serve as inspiration for novel technologies, and also vice versa, how technology gives us better clues in understanding natural systems.

The issue reflects very much the diversity and exciting science encompassed by the Sensor CDT in Cambridge, and a number of contributions are from scientists active within the CDT, including our very own student cohort, who developed a wireless sensor suite for assisted living.
