Nanogenerators

Extra

Researchers at the Georgia Institute of Technology in the US, led by Dr Zhong Lin Wang, have developed nanogenerators that (when working together) can produce three volts - the equivalent of two AA batteries.

The nanogenerators are made from zinc oxide nanowires, which generate electricity when flexed or strained - meaning any body movement from the beat of a heart to the stroke of a finger can generate power.

“While a few volts may not seem like much, additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering an iPod or charging a mobile phone,” says Wang.
