Scientists have devised a way to use heartbeat and blood flow to generate electricity to charge military equipment, and maybe even your cell phone one day.
Low-frequency vibrations from any source of movement, including a heartbeat, blood flow and even the wind against your clothes, creates mechanical stress, which in turn produces electricity through the cyclical stretching and releasing of specially designed nano thin, zinc oxide wires, according to researchers at Georgia Institute of Technology.
The new nano-scale "flexible charge pump" generator produces alternating current. The greater the strain rate, the more electricity generated.
"Quite simply, this … Read more
