Acoustical Cloaking Achieved

After already showing that simple man-made materials can be employed as invisibility cloaks or used to facilitate wireless power transmission, Duke University engineers have now demonstrated that these same materials can also make objects invisible to sound waves. The engineers designed, built and [...]

New Smartphone App Automatically Tags Photos

DURHAM, N.C. -- So much for tagging photographs with names, locations and activities yourself – a new cell phone application can take care of that for you. The system works by taking advantage of the multiple sensors on a mobile phone, as well as those of other mobile phones in the vicinity. Dubbed [...]

Novel Man-Made Material Could Facilitate Wireless Power

DURHAM, N.C. – Electrical engineers at Duke University have determined that unique man-made materials should theoretically make it possible to improve the power transfer to small devices, such as laptops or cell phones, or ultimately to larger ones, such as cars or elevators, without wires. This [...]

Light on Silicon Better than Copper?

DURHAM, N.C. -- Step aside copper and make way for a better carrier of information -- light. As good as the metal has been in zipping information from one circuit to another on silicon inside computers and other electronic devices, optical signals can carry much more, according to Duke University [...]

DNA Could Be Backbone of Next Generation Logic Chips

DURHAM, N.C. – In a single day, a solitary grad student at a lab bench can produce more simple logic circuits than the world’s entire output of silicon chips in a month. So says a Duke University engineer, who believes that the next generation of these logic circuits at the heart of computers will [...]

Next Generation Lens Promises More Control

Duke University engineers have created a new generation of lens that could greatly improve the capabilities of telecommunications or radar systems to provide a wide field of view and greater detail. But the lens they fashioned doesn’t look anything like a lens. While traditional lenses are made of [...]

DARPA-Funded Study to Detect Viral Infection Before Symptoms Appear

The Defense Advanced Research Projects Agency (DARPA), the research arm of the U.S. Department of Defense, has awarded Duke University $19.5 million for an effort led by the Duke Institute for Genome Sciences & Policy (IGSP) to design a portable, easy-to-use diagnostic device that can reveal [...]

Room's Ambience Fingerprinted By Cell Phone

DURHAM, N.C. -- Your smart phone may soon be able to know not only that you're at the mall, but whether you're in the jewelry store or the shoe store. Duke University computer engineers have made use of standard cell phone features – accelerometers, cameras and microphones – to turn the unique [...]

Lightning's Mirror Image, Only Much Bigger

DURHAM, N.C. -- With a very lucky shot, Duke University scientists have captured a one-second image and the electrical fingerprint of a huge jolt of lightning that flowed 40 miles upward from the top of an offshore tropical storm. These rarely seen, highly charged meteorological events are known as [...]
