Briefs: Materials
Metal-air batteries are one of the lightest and most compact types of batteries but when not in use, they degrade quickly, as corrosion eats away at their metal electrodes. While...
Briefs: Motion Control
Researchers have developed a fundamentally new type of rotary electrical contact that addresses the two limitations of conventional brush/slip ring technology: 1) short operating lifetime due to sliding-contact wear,...
Briefs: Electronics & Computers
In contrast with conventional light-emitting diodes (LEDs) that emit billions of photons simultaneously to form a steady stream of light, a single photon emitter (SPE) generates...

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 was...
Briefs: Manufacturing & Prototyping
Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the unusual behavior of some liquids...
Briefs: Materials
Researchers have created stretchable, rubbery semiconductors including rubbery integrated electronics, logic circuits, and arrayed sensory skins fully based on rubber materials. The semiconductors have...
Briefs: Electronics & Computers
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 of...
Briefs: Manufacturing & Prototyping
This invention applies to the field of sputtering, depositing SiGe thin films on sapphire substrates. It is a method of modifying the film growth...
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 does...

Waterproof Graphene Electronic Circuits
The many applications of graphene, an atomically-thin sheet of carbon atoms with extraordinary conductivity and mechanical properties, include the manufacture of sensors. These transform environmental parameters into electrical signals that can be processed and measured with a computer. Due to their...
Briefs: Energy
Anew material was developed that can extract the key ingredient in the most common form of plastic from a mixture of other chemicals while consuming far less energy than usual. The...
Briefs: Aerospace
When engineers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model the flow of air...
Briefs: Communications
A current-steering digital-to-analog converter (DAC) was developed that achieves improved switching times (up to 75% faster) in high-speed (gigahertz), high-resolution (8-14 bits)...
Briefs: Aerospace
NASA’s Langley Research Center has developed a new way to reduce the high-temperature heating requirement of sapphire substrates in wafer production. The growth of...
Briefs: Manufacturing & Prototyping
Unwanted porosity is typical to many manufacturing processes — from traditional casting to additive manufacturing (3D printing) — and is difficult to avoid entirely....

Software Could Help Prevent Arrhythmic Heart Disease
The heart’s pumping ability is controlled by electrical activity that triggers the heart muscle cells to contract and relax. In certain heart diseases such as arrhythmia, the organ’s electrical activity is affected.
Briefs: Manufacturing & Prototyping
Nearly all commercial products start as a CAD file — a 2D or 3D model with the product’s design specifications. One method that’s widely used to represent today’s 3D models is...
Briefs: Data Acquisition
Anew type of magnet — called a singlet-based magnet — was discovered that differs from conventional magnets in which small magnetic constituents align with one another to create a strong...
Briefs: Electronics & Computers
Traditionally, electronics are cooled using a heat sink that transfers the heat generated by the electronic system into the air or a liquid coolant. For the heat sink to work, it has to be...
