Nanogenerators powered by your heartbeat could replace batteries in five years, say chemists

Nanogenerators powered by your heartbeat could replace batteries in five years, say chemists: "In a few years, you may never have to recharge your phone again. Today scientists announced the first viable 'nanogenerator,' a tiny computer chip that gets its power from body movements like snapping fingers or - eventually - your heartbeat.

This technology, long anticipated by futurists, could replace batteries for small devices like MP3 players and mobile phones within a few years. For now, they can generate enough electricity to power a liquid crystal display and an LED. A group of researchers led by Georgia Tech's Zhong Lin Wang announced their groundbreaking discovery today at a meeting of the American Chemical Society in California."
