Remarkable New Clothing May Someday Power Your iPodŽ

The promise of piezoelectric fiber pairs

A scanning electron microscopy image showing piezoelectric zinc oxide nanowires

A scanning electron microscopy image shows the piezoelectric zinc oxide nanowires. The two sets of nanowires meet teeth-to-teeth, allowing the gold-coated microfibers to scrub those not coated with gold to produce electricity via a coupled piezoelectric-semiconducting process. This is the fundamental concept of a "power shirt."

Illustration of gold-coated microfibers that scrub uncoated microfibers to generate electricity

A schematic illustration of a "bottle-brush" structure shows nanowires arranged around a fiber. Microfibers coated with gold (yellow) scrub uncoated microfibers to produce electricity via a coupled piezoelectric-semiconducting process.
