Motion Converted To Electronic Signals For Tactile Imaging By Piezoelectric 'Taxel' Arrays
2013-04-25 21:27:07

Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes the world's first "electrified snail," which now joins the menagerie of cockroaches, rats, rabbits and other animals previously implanted with biofuel cells that generate electricity — perhaps for future spy cameras, eavesdropping microphones and other electronics — from natural sugar in their bodies.

Blinking numbers on a liquid-crystal display (LCD) often indicate that a device's clock needs resetting, but the blinking number on a small LCD signals the success of a five-year effort to power conventional electronic devices with nanoscale generators that harvest mechanical energy from the environment using an array of tiny nanowires.
