3D Printing of Flexible Circuits

A process was developed for 3D printing that can be used to produce transparent and mechanically flexible electronic circuits. The electronics consist of a mesh of silver nanowires that can be printed in suspension and embedded in various flexible and transparent plastics (polymers). This technology can enable...

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...

Briefs: Lighting

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...

Briefs: Medical

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...

Briefs: Manufacturing & Prototyping

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...

Briefs: Transportation

Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

Briefs: Lighting

An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...

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....

Briefs: Materials

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

Briefs: Sensors/Data Acquisition

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

Briefs: Photonics/Optics

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...

Briefs: Materials

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...

Briefs: Photonics/Optics

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...

Briefs: Transportation

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...

Briefs: Lighting

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...

Briefs: Automotive
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...
