Next, A Heart-Charged iPod

The Telegraph reports: “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. Hailed as a milestone, it can use tiny movements such as the pinch of a finger to generate power. …The technology works by using zinc oxide nanowires, which generate electricity when strained or flexed. This mean virtually any body movement – from walking to a heartbeat – can generate power.”
