Sticky composites

New battery technology employs multifunctional materials

Lithium-ion batteries power a vast array of modern devices, from cell phones, laptops, and laser pointers to thermometers, hearing aids, and pacemakers. The electrodes in these batteries typically comprise three components: active materials, conductive additives, and binders.

Now, a team of researchers at the University of Delaware has discovered a “sticky” conductive material that may eliminate the need for binders.  (more…)

GPS Not Working? A Shoe Radar May Help You Find Your Way

The prevalence of global positioning system (GPS) devices in everything from cars to cell phones has almost made getting lost a thing of the past. But what do you do when your GPS isn’t working? Researchers from North Carolina State University and Carnegie Mellon University (CMU) have developed a shoe-embedded radar system that may help you find your way.

“There are situations where GPS is unavailable, such as when you’re in a building, underground or in places where a satellite connection can be blocked by tall buildings or other objects,” says Dr. Dan Stancil, co-author of a paper describing the research and professor and head of NC State’s Department of Electrical and Computer Engineering. “So what do you do without satellites?” (more…)
