New way to control light

March 19, 2015 1:30 pm | by Univ. of Central Florida | News | Comments

A device resembling a plastic honeycomb, yet infinitely smaller than a bee’s stinger, can steer light beams around tighter curves than ever before possible, while keeping the integrity and intensity of the beam intact. The work introduces a more effective way to transmit data rapidly on electronic circuit boards by using light.

March 18, 2015 12:03 pm | by George Hunka, Tel Aviv Univ. | News | Comments

From computers, tablets and smartphones to cars, homes and public transportation, our world is more digitally connected every day. The technology required to support the exchange of massive quantities of data is critical. That's why scientists and engineers are intent on developing faster computing units capable of supporting much larger amounts of data transfer and data processing.

“Smart bandage” detects bed sores before they are visible

March 17, 2015 2:23 pm | by Sarah Yang, Univ. of California, Berkeley | Videos | Comments

Engineers at the Univ. of California, Berkeley, are developing a new type of bandage that does far more than stanch the bleeding from a paper cut or scraped knee. Thanks to advances in flexible electronics, the researchers have created a new “smart bandage” that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes, and while recovery is still possible.

New technology may double radio frequency data capacity

March 13, 2015 3:34 pm | by Holy Evarts, Columbia Univ. School of Engineering and Applied Science | News | Comments

A team of Columbia Engineering researchers has invented a technology, full-duplex radio integrated circuits (ICs), that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Up to now, this has been thought to be impossible: transmitters and receivers either work at different times or at the same time but at different frequencies.

Strength in numbers

March 4, 2015 4:37 pm | by Sonia Fernandez, Univ. of California, Santa Barbara | News | Comments

When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers by comparison. But, before that happens, quantum physicists will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit.

Breakthrough in OLED technology

March 2, 2015 12:27 pm | by Jason Socrates Bardi, American Institute of Physics | News | Comments

Organic light-emitting diodes (OLEDs), which are made from carbon-containing materials, have the potential to revolutionize future display technologies, making low-power displays so thin they'll wrap or fold around other structures, for instance. Conventional LCD displays must be backlit by either fluorescent light bulbs or conventional LEDs whereas OLEDs don't require back lighting.

Innovative wireless sensor technology yields better energy efficiency

March 2, 2015 8:17 am | by Sara Shoemaker, Oak Ridge National Laboratory | News | Comments

Regulating comfort in small commercial buildings could become more efficient and less expensive thanks to an innovative low-cost wireless sensor technology being developed by researchers at Oak Ridge National Laboratory. Buildings are responsible for about 40% of the energy consumed in the U.S. Studies indicate that advanced sensors and controls have the potential to reduce the energy consumption of buildings by 20 to 30%.

QR codes engineered into cybersecurity protection

February 27, 2015 10:03 am | by Colin Poitras, UConn | News | Comments

QR, or quick response, codes have been used to convey information about everything from cereals to cars and new homes. But, Univ. of Connecticut researchers think the codes have a greater potential: protecting national security. Using advanced 3-D optical imaging and extremely low light photon counting encryption the team has taken a QR code and transformed it into a high-end cybersecurity application.

Smartphones could tell consumers what's in food

February 26, 2015 9:09 am | by Mary Clare Jalonick, Associated Press | News | Comments

In the ever-complicated debate over labeling of genetically modified foods, Agriculture Secretary Tom Vilsack says he has an idea: use your smartphone. Vilsack told members of Congress on Wednesday that consumers could just use their phones to scan special bar codes or other symbols on food packages in the grocery store. All sorts of information could pop up, such as whether the food's ingredients include genetically modified organisms.

Radio chip for the Internet of things

February 23, 2015 7:46 am | by Larry Hardesty, MIT News Office | News | Comments

At this year’s Consumer Electronics Show, the big theme was the “Internet of things”: the idea that everything in the human environment could be equipped with sensors and processors that can exchange data, helping with maintenance and the coordination of tasks. Realizing that vision, however, requires transmitters that are powerful enough to broadcast to devices dozens of yards away but energy-efficient enough to last for months.

Fibers made by transforming materials

February 20, 2015 8:26 am | by David L. Chandler, MIT News Office | News | Comments

Scientists have known how to draw thin fibers from bulk materials for decades. But a new approach to that old method, developed by researchers at Massachusetts Institute of Technology, could lead to a whole new way of making high-quality fiber-based electronic devices. The idea grew out of a long-term research effort to develop multifunctional fibers that incorporate different materials into a single long functional strand.

Electronics you can wrap around your finger

February 10, 2015 11:51 am | by American Institute of Physics | News | Comments

Electronic devices have shrunk rapidly in the past decades, but most remain as stiff as the same sort of devices were in the 1950s: a drawback if you want to wrap your phone around your wrist when you go for a jog or fold your computer to fit in a pocket. Researchers from South Korea have taken a new step toward more bendable devices by manufacturing a thin film that keeps its useful electric and magnetic properties even when highly curved.

Nanoscale solution to big problem of overheating in microelectronic devices

February 6, 2015 10:01 am | by Megan Hazle, Univ. of Southern California | News | Comments

Anyone who has ever toasted the top of their legs with their laptop or broiled their ear on a cell phone knows that microelectronic devices can give off a lot of heat. These devices contain a multitude of transistors, and although each one produces very little heat individually, their combined thermal output is significant and can damage the device.
