Nano-fibers to provide power

US researchers have created a nano-fiber textile that harvests energy from movement, paving the way for clothing that could one day power an iPod or other wearable electronic devices, according to a study published Wednesday.

Using the same mechanical principle as a self-winding watch, but on scale measured in billionths of a meter, tiny nano-generators can scavenge “wasted” energy from sound waves, vibrations, or even the human heart beat.

The fibers, developed by a team of scientists at the Georgia Institute of Technology led by Zhong Lin Wang, are covered with pairs of zinc oxide nanowires that produce tiny pulses of electricity in response to friction.
