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...

For decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible—even routine—to place millions of transistors on a single silicon chip. But transistors based on semiconductors can only get so small. “At the rate the current technology is progressing, in 10 or 20 years, they won’t be able to get any smaller,” said physicist Yoke Khin Yap of Michigan Technological University. “Also, semiconductors have another disadvantage: they waste a...

Nanowires Precisely Positioned Using Sound Waves
2013-06-19 10:28:48

Penn State The smaller components become, the more difficult it is to create patterns in an economical and reproducible way, according to an interdisciplinary team of Penn State researchers who, using sound waves, can place nanowires in repeatable patterns for potential use in a variety of sensors, optoelectronics and nanoscale circuits. "There are ways to create these devices with lithography, but it is very hard to create patterns below 50 nanometers using lithography," said Tony Jun...

Ulsan National Institute of Science and Technology(UNIST) Eye contact lenses, picture-taking and scanning, possibly, a wearable black box A hybrid transparent and stretchable electrode could open the new way for flexible displays, solar cells, and even electronic devices fitted on a curvature substrate such as soft eye contact lenses, by the UNIST(Ulsan National Institute of Science and Technology) research team. Transparent electrodes are in and of themselves nothing all that...

Solar Power Through Painted On Organic Photovoltaics
2013-05-14 05:58:22

Lee Rannals for redOrbit.com - Your Universe Online Researchers at the University at Buffalo are developing a technique that could allow for solar panels to be painted on some day. The team wrote in the journal Advanced Materials they are helping to develop a new generation of photovoltaic cells that produce more power and cost less to manufacture than today's solar panels. These devices are processed in liquid form and can be applied to a variety of surfaces. “Compared with...

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...

Nanowires Grown On Graphene Have Surprising Structure
2013-04-24 12:04:44

University of Illinois When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired trait for many advanced electronics applications. Led by professor Xiuling Li, in collaboration with professors Eric Pop and Joseph Lyding, all professors of electrical and...

University of Cincinnati research describes discovery of a new structure that is a fundamental game changer in the physics of semiconductor nanowires. There´s big news in the world of tiny things. New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts...

Nanowires May Mean More Efficient, Cheaper Solar Panels
2013-04-08 19:16:36

Enid Burns for redOrbit.com — Your Universe Online Nanowires could be the answer for constructing solar panels with less materials and lower costs. Researchers at the Ecole Polytechnique Federale De Lausanne (EPFL) are working on new technology to advance solar panels. New research on tiny filaments called nanowires has made some promising findings. Influenced by nature, researcher Anna Fontcuberta i Morral looked at how trees in a forest stand upright to collect energy from the...

Penn Engineers Have Enabled 'Bulk' Silicon Enabled To Emit Visible Light For The First Time
2013-03-28 12:43:54

University of Pennsylvania Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass those limitations, but the components of such computers require semiconductors that can emit light. Now, research from the University of Pennsylvania has enabled "bulk" silicon to emit broad-spectrum, visible light for the first time, opening the possibility...
