Nokia and scientists at Queen Mary College, University of London, have recently successfully developed techniques for using sound to generate electricity.

Four years ago, scientists in South Korea had proposed using sound to generate electricity, using sound as a power source to drive nano-generators based on piezoelectric nanowires. However, with other mechanical energy sources (such as the heartbeat, blood flow and other movements), sound machinery can produce, collect the electricity is relatively small.

Similar to previous techniques, Nokia and British scientists sprayed liquid zinc oxide onto a plastic sheet and placed it on a chemical mixture to heat up the surface of the plastic sheet at 90 ℃ to produce ZnO nanorods, sandwiched between two aluminum foil-contact sheets, to obtain the voltage.

The prototype, which is nearly nearly as close to the Nokia Lumina 925, can generate 5V of current in daily noise, enough to recharge the phone. The technology will not only solve the problem of mobile devices such as mobile phones, but also reduce battery pollution.

In fact, think of the use of sound power generation manufacturers There are many, it is said that the European mobile giant Orange Company, proposed a similar idea, sound generation T-shirt (Sound Charge shirt). In the middle of the T-shirt is a A4 film, which absorbs sound waves and converts them into electricity for storage. As long as the surrounding sound is over 80 decibels, 6W of electricity can be generated.
