Submission + - The Human Body Could be Used to Charge Portable Devices (ibtimes.co.uk) 1

concertina226 writes: Chinese researchers at Peking University in Beijing have invented a small generator that uses the human body as an electrode to power devices without requiring batteries.

The researchers have created a new material known as single-friction-surface triboelectric generator (STEG). They covered the screen on a smartphone with a layer of the transparent STEG composite material and also added a body contact electrode, which is used to conduct electricity, to the casing and the frame of the phone.

After repeated tapping and patting, when the palm of a hand or fingers came into contact with the phone, electric charges moved back and forth between the electrode and the charged skin, transferring electricity to the phone.
