Nanowire-Embedded Fabrics Generate Electricity from Motion

Illustration shows the concept behind a microfiber nanogenerator. Microfibers coated with gold (yellow fibers) scrub the nanofibers that are not coated with gold (green) to produce electricity through a coupled piezoelectric-semiconductor process.

Nanowire-Embedded Fabrics Generate Electricity from Motion

Georgia Tech Professor Zhong Lin Wang shows a microfiber nanogenerator composed of a pair of entangled fibers. Both fibers are coated with zinc oxide nanowires; one fiber is additionally coated with gold. When rubbed together, they generate electrical cur
