Researchers at Michigan State University have discovered a way to capture energy from human motion using a nanogenerator.

The film-like device – as thin as a sheet of paper – can be adapted to many applications and sizes.

The scientists at Michigan State used it to successfully operate an ‘LCD touch screen, a bank of 20 LED lights and a flexible keyboard, all with a simple touching or pressing motion and without the aid of a battery’. It can also be folded to create additional power.

Published in the journal Nano Energy, the findings indicate “we’re on the path toward wearable devices powered by human motion,” according to Nelson Sepulveda, associate professor of electrical and computer engineering and lead investigator of the project.

“What I foresee, relatively soon, is the capability of not having to charge your cell phone for an entire week, for example, because that energy will be produced by your movement,” he said.
