Advanced electronics are indispensable in modern warfare, but locating and tracking them all on the field of battle is almost impossible. To prevent valuable and strategic technology from falling into enemy hands, DARPA has announced the Vanishing Programmable Resources program, which has the aim of improving “transient” electronics, or electronics capable of dissolving into the environment around them.
Existing optical beamsteering assemblies for technologies like LADAR, which scans a field of view with a laser to determine distance, are typically mechnical, bulky, slow, and inaccurate. In an effort to design a better, scalable technology, DARPA researchers have recently demonstrated the most complex optical phased array ever built onto a 2D chip.
The world's love affair with gadgets—many of which contain hazardous materials—is generating millions of tons of electronic waste annually. Now, Purdue and Tuskegee universities are leading an international effort to replace conventional electronics with more sustainable technologies and train a workforce of specialists to make the transition possible.
Not everything there is “high-tech”, but the annual Consumer Electronics Show is a great place to see the newest and most fanciful products to reach the market each year. From the iPotty for toddlers to the 1,600-pound (725-kg) mechanical spider and the host of glitch-ridden "smart" TVs, the International CES show is a forum for gadget makers to take big—and bizarre—chances.
VPG's new System 8000 StrainSmart data acquisition system features eight software-configurable input channels with RJ-45 connectors. It can accept signals from strain gages or strain-gage-based transducers, thermocouples, or high-level voltage sensors.
Researchers at Georgia Institute of Technology are trying to open the world of tablets to children whose limited mobility makes it difficult for them to perform the common pinch and swipe gestures required to control the devices. In their Access4Kids wireless input device, a sensor system to translate physical movements into fine-motor gestures to control a tablet.
A team at Wake Forest University has used a nano-engineered polymer matrix to convert electrical charge charge into light, creating an entirely new bulb based on field-induced polymer electroluminescent technology. Unlike conventional fluorescent bulbs, these new lights will not flicker, hum, or shatter, and they offer a soft, white light.
A research team in Korea developed a powerful audio rendering technology that reproduces a desired sound field more clearly and accurately. The system, which they call a “Virtual Sound Ball”, establishes a virtual array of loudspeakers and a virtual sound source within that system. Application of acoustical mathematics and a “spatial equalizer” allows the user to more accurately reproduce 3D sound effects with an existing speaker setup.
A research team from the University of California, Santa Barbara and Portland State University has retrieved a sensor containing previously unavailable data about changes in chemistry or acidification in the remote waters of McMurdo Sound in Antarctica. The device collected data through June, when the battery expired in the harsh polar sea.
Thanks to an ultrasensitive accelerometer—a type of motion detector—developed by researchers at the California Institute of Technology and the University of Rochester, a new class of microsensors is a step closer to reality. Instead of using an electrical circuit to gauge movements, this accelerometer uses laser light and is so sensitive it could be used to navigate shoppers through a grocery aisle or even stabilize fighter jets.
Through a new website unveiled Wednesday, Google is opening a virtual window into the secretive data centers where an intricate maze of computers process Internet search requests, show YouTube video clips, and distribute email for millions of people. The photographic access to Google's data centers coincides with the publication of a Wired magazine article about how the company builds and operates them.
People can let their fingers—and hands—do the talking with a new touch-activated system that projects onto walls and other surfaces and allows users to interact with their environment and each other. Developed at Purdue University, the "extended multitouch" system allows more than one person to use a surface at the same time and also enables people to use both hands, distinguishing between the right and left hand.
Conventional defibrillators, known as transvenous defibrillators, are implanted with wires, called the leads, that snake through veins into the heart. Not all patients are suitable for a conventional defibrillator, and complex and invasive surgery is often involved when they are. What makes a new device at the University of Ottawa Heart Institute special is that it is entirely subcutaneous. No part of it actually touches the heart.
Researchers at Rice University are designing transparent, two-terminal, 3D computer memories on flexible sheets that show promise for electronics and sophisticated heads-up displays. The technique is based on the switching properties of silicon oxide.
Digital cameras and camcorders deliver high resolution film sequences that are several gigabytes in size. These can take several minutes to transfer wirelessly to your home computer via Bluetooth. A researcher in Germany has come up with a speedier alternative: a “multi-gigabit communication module” that is six times faster than a USB cable.
Tiny, fully biocompatible electronic devices that are able to dissolve harmlessly into their surroundings after functioning for a precise amount of time have been created by a research team led by biomedical engineers. Dubbed "transient electronics," the new class of silk-silicon devices promises a generation of medical implants that never need surgical removal, as well as environmental monitors and consumer electronics that can become compost rather than trash.
A prototype sensor array built by Massachusetts Institute of Technology engineers can be worn on the chest and automatically maps the wearer’s environment, recognizing movement between floors. The prototype system is envisioned as a tool to help emergency responders coordinate disaster response.
It’s a bit like Twitter, only instead of 140 words or less, the electronic tags needed by ornithologists researching the behavior of small birds had to 1 gram or less. This type of miniaturization for a rugged, mobile tag was previously unavailable until a biologist teamed up with an electrical engineer at Scotland’s University of St. Andrews.
