Smartphones can be recharged using your voice

Moreover, with the help of a new way to convert sound into electricity can recharge the device using the background noise or music, wrote The Daily Telegraph. As the project manager, Dr. Sun-Woo Kim from the Institute of Nanotechnology at Sunkyunkvanskom University in Seoul, the new technology will find application in various fields. Generate electricity will also be able soundproof walls near highways, which absorb sound energy passing car. The technology of Kim and his colleagues are microscopic filaments of zinc oxide, laid between two electrodes. Under the influence of ambient sounds plate begins to vibrate and cause the reduction of tiny filaments. As a result of this movement produces electric current, which is quite enough to charge your mobile phone. The prototype device with this technology is able to convert the sound volume 100 decibels (the equivalent noise passing cars) to 50 millivolts of electricity. Although this power is still insufficient to fully charge a mobile phone, the researchers hope that other stuff will make more of an electric current at a lower level of the sound Previously, scientists have developed prototypes of devices that use a heartbeat for charging MP3-player, and Nokia filed a patent application on the device, charging of bodily movements.
