Energy is stored within a loop – it just depends on what form it comes in. Of course, we do know that moving around generates juice as well when properly harnessed, but Professor Zhong Lin Wang, director of the Center for Nanostructure Characterization at Georgia Tech, has come up with something that might just change the way you view clothes – his latest development will see the embedding of tiny piezoelectric nanowires in flexible materials to make it possible to fabricate nanowire-based generators which can harvest sufficient mechanical energy in order to juice small devices, such as light-emitting diodes and a liquid-crystal display. Does this mean your iPod could then be powered by your clothing in the future? We suppose those who fidget a lot or tend to shake their legs when seated will have an advantage over the proper, stiff upper lipped demeanor.
