Keynote Speaker 3: Eric Yeatman – Ambient and Wireless Power Sources for Wireless Sensors
Wireless electronic devices have been proliferating in recent years, and will continue to do so. Most are powered by batteries, and removing the burden of recharging or replacing these is becoming ever more attractive. Wireless sensors are a particularly compelling application, because in many desired applications they will be large in number, and difficult to access, while having modest power requirements. At Imperial College London, we have developed a variety of alternative powering methods, including kinetic energy harvesters, dynamic thermoelectric harvesters, resonant inductive charging systems, and ultrasonic power delivery. I will present these devices and methods, and also demonstrate a new concept called synthetic sensor networks, in which drones or other mobile robots visit widely scattered sensors to autonomously collect data and deliver wireless power. Finally I will applications for such systems, and possible future developments.
