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.
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.
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.
Real-time dynamic holographic displays, long the realm of science fiction, could be one step closer to reality, after researchers from the Univ. of Cambridge developed a new type of pixel element that enables far greater control over displays at the level of individual pixels.
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.
The editors of R&D Magazine have announced an eligibility extension for products to be entered into the 2015 R&D 100 Awards. The 2015 R&D 100 Awards will honor products, technologies and services that have been introduced to the market between January 1, 2014 and March 31, 2015.
Researchers have used an advanced model to simulate in unprecedented detail the workings of "resistance-switching cells" that might replace conventional memory for electronics applications, with the potential to bring faster and higher capacity computer memory while consuming less energy. These electromechanical "metallization cells" rapidly switch from high resistance to low resistance.
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.
Lawrence Livermore National Laboratory researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored. The research could lead to an improvement in the capacity and efficiency of electrical energy storage systems needed to meet the burgeoning demands of consumer, industrial and green technologies.
From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets’ versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome.
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.
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, 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.
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.
Univ. of Tokyo researchers have developed a "fever alarm armband," a flexible, self-powered wearable device that sounds an alarm in case of high body temperature. The flexible organic components developed for this device are well-suited to wearable devices that continuously monitor vital signs including temperature and heart rate for applications in health care settings.
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.
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.
Computer chips’ clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations in parallel. But the ways in which a chip carves up computations can make a big difference to performance.
The future of electronics could lie in a material from its past, as researchers from The Ohio State Univ. work to turn germanium, the material of 1940s transistors, into a potential replacement for silicon. At the American Association for the Advancement of Science meeting, Asst. Prof. of Chemistry Joshua Goldberger reported progress in developing a form of germanium called germanane.
Multiphysics software has become the simulation tool for designing and optimizing new products. This software can quickly provide designers with multiple options for critical product designs across a range of environmental, physical and chemical operating conditions. Recently introduced multiphysics software enhancements also allow simplified use of these simulation tools across a broader range of users.
Researchers invented the Lab-in-a-Box— a box that contains assorted sensors and software designed to monitor a doctor’s office, particularly during consultations with patients. The goal is to analyze the physician’s behavior and better understand the dynamics of the interactions of the doctor with the electronic medical records and the patients in front of them.
Although wearable devices have received significant attention for their ability to track an individual’s physical activity, most smartphone applications are just as accurate.
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.
Overheating is a major problem for the microprocessors that run our smartphones and computers. But a team of scientists have made a breakthrough that should enable engineers to design microprocessors that minimize that problem: They have developed a thermal imaging technique that can “see” how the temperature changes from point to point inside the smallest electronic circuits.
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.
