Future smartphones could be charged with noise

(WXYZ) - Power cords, who needs them?

Scientists from Queen Mary University of London and Nokia teamed up to develop a way to charge a phone with noise.

The team created what is called a nanogenerator that would use everyday background noise--think traffic, music, cheering or even or own voices to charge a mobile phone.

Zinc oxide played a pivotal role in their project, the material creates a voltage when it's squashed or stretched--so, with some good ole fashioned sound vibrations, energy could be harvested.

One of the scientists on the project says on the school's website that he hopes that his team has brought this technology closer to viability.
