Future iPods could be powered by the human heartbeat

Scientists have developed a tiny chip which uses the body’s own movement to generate power, reports The Telegraph.
The team, presenting their findings at the National Meeting & Exposition of the American Chemical Society, have used it to power LCD displays and diodes, as well as to transmit a radio signal once its generated power has been stored.
Dr Zhong Lin Wang, of Georgia Institute of Technology said: "This development represents a milestone toward producing portable electronics that can be powered by body movements without the use of batteries or electrical outlets. Our nanogenerators are poised to change lives in the future. Their potential is only limited by one’s imagination."
The technology uses zinc oxide nanowires that generate electricity when strained or flexed by virtually any movement from walking to a heartbeat.
"Additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering larger electronics, such as an iPod or charging a cell phone."
