Power generated from flowing blood, simple body movements or a gentle breeze could one day be converted to electricity to charge iPods, cell phones and other personal electronic devices.

Researchers reported today they can harvest energy by converting low-frequency vibrations, like simple body movements, the beating of the heart or movement of the wind, into electricity by using zinc oxide nanowires that conduct the electricity.

The nanowires are piezoelectric — they generate an electric current when subjected to mechanical stress.

Other schemes have been devised to generate power in a backpack as you hike or from a device attached to the knee. Those are comparatively bulky, however.
