Self-Powered, Washable, Wearable Displays

Clothing usually is formed with textiles and has to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. To solve this problem, a textile-based, wearable display module technology...

Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential...

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many...

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It...

Single-Crystal SiGe/Sapphire Epitaxy

NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....

One current method to build a semiconductor superlattice — materials comprised of alternating layers of ultra-thin, two-dimensional sheets only one or a...

When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....

Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened...

Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...

Positional sensors have applications where a very accurate measurement of position is needed over a limited range. One example of such an application is in manipulation of a...

A driverless car is making its way through a winding neighborhood street, about to make a sharp turn onto a road where a child’s ball has just rolled. Although no person in the car can see that ball, the...

Crew time on the International Space Station (ISS) is extremely limited for any operations on science payloads. Autonomous science experiments in small, self-contained, cubical payloads are highly desirable...

Wireless Charging of Moving Electric Vehicles

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles. Researchers have wirelessly transmitted electricity to a nearby moving object, which could advance...
