Devices that use the wasted mechanical energy from clothing movements or even a heartbeat seem far out, if not just a bit creepy, but new advances in nanogenerators are making such energy-scavenging electronics possible.
Now researchers at Georgia Tech have made the first nanowire-based generators that can harvest sufficient mechanical energy to power small devices, including light-emitting diodes and a liquid-crystal display. Read More >
