As electronic circuits get smaller and become less power hungry, small amounts of energy in our surroundings can be used to power them up. For bio-implantable and wearable devices it is possible to extract energy from body movements. Until now, three main transducers have been introduced for energy scavenging purposes, i.e. piezoelectric, electromagnetic and electrostatic. In electrostatic method...
