Scientists from the National University of Singapore discovered an innovative way to generate electricity by friction of the human skin, which can be used to power the electronics on his body - for example, "smart" watches or bracelets. Development is a flexible miniature device (about the size of a postage stamp) that converts static electricity into USAble energy.

In the mini-generator twofold: one is attached to the skin, and the other covered with a thin silicon wafer and a gold film. Between the two surfaces of the protrusions are made of silicone rubber, which increase the area of contact, friction and the amount of energy produced. The machine produces electricity as a result of the triboelectric effect. It occurs when two surfaces are in close contact with each other.

How does the invention have been shown at the conference IEEE MEMS 2015, which took place last week. One person put an overlay on the forearm, the other - on the throat, after which they began to make everyday muscle movements: talk and squeeze his hand into a fist. As a result of these steps was obtained voltage 7.3-7.5 volt. When tapped on the device, it could already produce 90 volts, and that is enough to power multiple LED bulbs.



In 2011, scientists learned how to generate electricity from the human respiratory tract. They have created a special film that converts the air flow coming out of the nostrils with a speed of up to two meters per second, into electrical energy. Technology research based on the piezoelectric effect when the electric power can be obtained from the mechanical oscillations of special material. In this case it was micron-thick film made of polivinilipdenftorida (PVDF).

Earlier piezoelectric effect was found other uses associated with the transformation of the vibrations of the road from the movement of vehicles into electricity. The generated electricity can be stored in batteries and supply roadside traffic signs or traffic lights.
