Al writes "Researchers at Georgia Tech have come up with the ideal way to test a new peizo-electric device that efficiently harvests power from bio-movement — attaching it to a hamster. The device contains a series of zinc-oxide nanowires mounted on top of a flexible plastic surface. As the plastic bends, the wires generate around a nanowatt of power. The Georgia Tech team, led by Zhong Lin Wang, wanted to show that their device could produce power from irregular movements so they attached it to a tiny hamster jacket. They also tried attaching it to a volunteer's finger. Here's a video of the hamster wearing his piezo-power outfit."
