    Apple iPod '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.

    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.

    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 latest device is thousands of times more powerful than its predecessors, allowing scientists to take the technology out of the lab for the first time.

    Dr Wang said: "If we can sustain the rate of improvement, the nanogenerator may find a broad range of other applications that require more 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.

    Dr Wang's team worked to capture and combine the power of millions of the nanowires, which are so small that 500 could fit in a human hair.

    Five nanogenerators working together produced about 1 micro ampere output current at 3 volts about the same voltage generated by two regular AA batteries.

    Let's just say that I won't be surprised to see Steve jobs walking around with an iPod Touch embedded in his chest.
