Nanogenerators may spark miniature machines
April 14, 2006Devices convert simple motion into electricity
Researchers at the Georgia Institute of Technology have crafted tiny nanowires that generate electricity when they vibrate. Just like the quartz crystal in a watch, the zinc-oxide nanowires are piezoelectric, which means bending causes them to produce an electrical charge.
Only 20-40 billionths of a meter in diameter, each fiber partners with millions of others to form a nanogenerator capable of producing significant amounts of energy from the slightest activity. According to the researchers, motions from body movement, the stretching of muscles and even the flow of liquids should be able to generate electric charges in the wires-perfect for implantable medical devices, "smart" apparel and a variety of other applications.

Remarkable new clothing may someday power your iPod
Nanotechnology researchers at the Georgia Institute of Technology are developing a shirt that harvests energy from the wearer's physical motion and converts it into electricity for powering small electronic devices worn by soldiers in the field, hikers and other users.
Fiber-based nanotechnology in clothing could harvest energy from physical movement
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy.
Nanogenerator provides continuous power by harvesting energy from the environment
Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow.
Cheaper LEDs from breakthrough in zinc oxide (ZnO) nanowire research, Nano Letters study says
Engineers at UC San Diego have synthesized a long-sought semiconducting material that may pave the way for an inexpensive new kind of light emitting diode (LED) that could compete with today's widely used gallium nitride LEDs, according to a new paper in the journal Nano Letters.
Nanogenerators convert mechanical energy to electricity for self-powered devices
Researchers have developed a new technique for powering nanometer-scale devices without the need for bulky energy sources such as batteries.
