New Technology Allows You To Charge Your Mobile Using Sound

Nokia and a team of scientists from the Queen Mary University of London have teamed up with to create a smartphone which can be powered by using  energy-harveting ‘nanogenerators’ that can react to sound vibrations and create electricity.

The technology is based on a concept called the piezoelectric effect, which describes how nanowires made from zinc oxide produce an electrical current when they’re subjected to some kind of mechanical stress, such as being squashed, stretched or bent. The Korean researchers discovered that these tiny nanowires were so sensitive, they’d bend in response to the pressure of sound waves. The team found that when they installed a device using the wires in their smartphone prototype, and exposed it to sounds like traffic, human voices, and music, it was able to generate five volts, which is enough to charge a mobile phone.

“Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept,” said one of the team, engineer Joe Briscoe, in a press release. “We hope that we have brought this technology closer to viability.”
