Apple iPhone ‘could be charged by the human heart’



“The human heartbeat could be used to power an ipod after scientists developed a tiny chip which uses the body’s own movement to generate power. Scientists hope that as the nanotechnology used in the chip evolves, it could lead to electronics which don’t require batteries or mains power,” The Telegraph reports. “Hailed as a milestone, it can use tiny movements such as the pinch of a finger to generate power.”
“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,” The Telegraph reports. “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 Telegraph reports, “Five nanogenerators working together produced about 1 micro ampere output current at 3 volts about the same voltage generated by two regular AA batteries. Dr Wang said: ‘While a few volts may not seem like much, it has grown by leaps and bounds over previous versions of the nanogenerator. Additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering larger electronics, such as an iPod or charging a cell phone.’”
