Latest Micropower Stories
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.

Human gait could soon power portable electronics.
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.
Researchers at the Georgia Institute of Technology have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires.
By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy.
U.S. scientists say they've developed a small-scale generator that produces alternating current by the cyclical stretching and releasing of zinc oxide wires.
Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded.
