In a win for sustainable energy, scientists have announced that they are in the process of utilizing nanotechnology to create self-generated power. While still in the experimental stages, the goal would allow for any “work” done by and to the human body to generate energy that could be later channeled into portable devices from the iPhone to PSP.
Presenting their findings at the American Chemical Society, Dr. Zhong Lin Wang of the Georgia Institute of Technology explained the technology to The Telegraph:
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.
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.
