New Device Can Recharge Wireless Gadgets While Walking
2014-07-03 03:11:17

National Science Foundation By the end of 2014, Earth will be home to more mobile electronic devices than people. Smartphones, tablets, e-readers, not to mention wearable health and fitness trackers, smart glasses and navigation devices--today's population is more plugged in than ever before. But our reliance on devices is not problem-free: Wireless gadgets require regular recharging. While we may think we've cut the cord, we remain reliant on outlets and charging stations to...

Harvesting Wasted Power Using TriboElectrification
2013-12-12 12:54:03

[ Watch the video: Harvesting the World's Mechanical Energy ] Brett Smith for redOrbit.com - Your Universe Online From ocean waves to the action of walking across a floor, energy is all around us. Now, a materials scientist from Georgia Tech has developed a system to capture that “wasted energy” and convert it into electricity. By using a phenomenon known as the triboelectric effect, a team led by Zhong Lin Wang has been able to create significant amounts of electric power by...

Your Signature In Lights
2013-08-12 06:20:58

Georgia Institute of Technology Researchers at the Georgia Institute of Technology want to put your signature up in lights – tiny lights, that is. Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure – from a signature or a fingerprint – directly into light signals that can be captured and processed optically. The sensor device could provide an artificial sense of touch, offering sensitivity comparable to that...

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

Georgia Institute of Technology 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 arrays include more than 8,000 functioning piezotronic transistors, each of...

New Carbon Form Can Indent Diamond
2012-08-17 09:33:27

April Flowers for redOrbit.com - Your Universe Online A new form of very hard carbon clusters capable of indenting diamond has been observed by a team of Carnegie Institution for Science researchers. The carbon clusters are unusual in their mix of crystalline and disordered structures and have potential applications for a range of mechanical, electronic, and electrochemical uses. The team, led by Lin Wang, published their findings in the August 17, 2012, issue of Science. Carbon...

By Harnessing Friction Between Surfaces, Triboelectric Generator Produces Electricity
2012-07-10 10:51:47

Polymer power Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us — this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this "triboelectric" generator could provide alternating current (AC) from activities such as walking. The triboelectric generator could supplement power produced by nanogenerators that...

Image 1 - Zinc Oxide Microwires Improve Performance Of Light-emitting Diodes
2011-11-01 03:46:47

Piezo-phototronic effect Researchers have used zinc oxide microwires to significantly improve the efficiency at which gallium nitride light-emitting diodes (LED) convert electricity to ultraviolet light. The devices are believed to be the first LEDs whose performance has been enhanced by the creation of an electrical charge in a piezoelectric material using the piezo-phototronic effect. By applying mechanical strain to the microwires, researchers at the Georgia Institute of Technology...

Biological interface Taking advantage of the unique properties of zinc oxide nanowires, researchers have demonstrated a new type of piezoelectric resistive switching device in which the write-read access of memory cells is controlled by electromechanical modulation. Operating on flexible substrates, arrays of these devices could provide a new way to interface the mechanical actions of the biological world to conventional electronic circuitry. The piezoelectrically modulated resistive memory...
