Scientists are hoping that human heartbeat could be used to charge electronics which don’t require batteries such as an iPod. This comes after the development of a tiny chip which uses human body movements to generate power.
The team from National Meeting and Exposition of the American Chemical Society demonstrated their project by powering LCD displays and diodes.
The chip is actually made up of millions of zinc oxide nanowires, which generate electricity when flexed or strained. It means even a pinch of finger can generate power. A combination of five nanogenerators usually produce about 1 micro ampere output current at 3 volts which is equivalent to two regular AA cells.
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. These nanogenerators are poised to change lives in the future. Their potential is only limited by one’s imagination. If we can sustain the rate of improvement, the nanogenerator may find a broad range of other applications that require more power. 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.
Scientists have described this as a “milestone” in the field of nanotechnology.
