Scientists Want to Help Power Your Phone by Talking to It

A group of scientists from the university of Sungkyunkwan in South Korea have apparently developed a new technology which converts sound waves into electrical energy. With this concept, smartphones will be able to charge from any sound source, from talking to music and even highway traffic noise.

“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.” Dr. Sang-Woo Kim, a researcher involved in the project, stated.

The current outcome involves a prototype that converts around 100 decibels to 50 millivolts of electricity. This is done with a pad which absorbs sound waves and causes zinc oxide wires mounted between electrodes to compress and release, creating an electrical current that can be used to charge a battery.

While the generated electricity so far isn’t enough to power a whole phone, Dr. Kim stated that different materials can be used in the future to get better results. The current prototype however can already be beneficial for small, low-power sensors and implantable devices.
