Smart systems powered by triboelectric generators
Alice Zhang, Beijing University
As is well known, energy crises are becoming a worldwide problem and researchers are making every effort to search for the green and renewable energy source. To solve the problem, self-powered system has been proposed, which focuses on harvesting energy from the ambient environment. In 2012, utilizing the friction to generate energy based on the combination of triboelectric and electrostatic effect is presented as triboelectric nanogenerators (TENGs) which can be applied to biomedical and environmental systems as a power supply or a self-powered active sensor.
Sandwich TENGs have achieved an energy volume density of 53.4 mW/cm3 at 465 V and 13.4 µA/cm2. A transparent and flexible single-friction-surface triboelectric generator (STEG) can be applied for powering smart systems, such as touch panels, cell phone, artificial skins, sensor network nodes etc.
