"Nanogenerator Powers Up"

 

 

Devices that harvest wasted mechanical energy could make  many new advances possible—including clothing that recharges personal  electronics with body movements, or implants that tap the motion of blood or  organs. But making energy-harvesting devices that are compact, flexible, and,  above all, efficient remains a big challenge. 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... In a paper published online last week in the journal  Nano Letters, [Zhong Lin] Wang's group describes using a  nanogenerator containing more nanowires, over a larger area, to drive a small  liquid crystal display.
