Katia Moskvitch reports for BBC:

Taking a stroll may soon be enough to re-charge your mobile phone, after US researchers developed a way to generate electricity from human motion.

Kinetic charging is already used in some low power devices such as watches and sensors.

The University of Wisconsin team published its study in the journal Nature Communications.

“Humans, generally speaking, are very powerful energy-producing machines,” said Professor Tom Krupenkin from the university’s mechanical engineering department.

“While sprinting, a person can produce as much as a kilowatt of power.”

That, according to the scientists, is more than enough to power a standard mobile phone.
