Sound Into Electrical Energy

The future, you could charge your cell phone just by chatting.

Researchers at South Korea’s Sungkyunkwan University have developed a new technology that converts soundwaves into electrical energy, The Telegraph reports. With the sound-harvesting tech, batteries could be charged by everything from the human voice and music to the sound of highway traffic.

Researcher Dr. Sang-Woo Kim said, “The sound that always exists in our everyday life and environments has been overlooked as a source. This motivated us to realise power generation by turning sound energy from speech, music or noise into electrical power.”
