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...

Imagine trying to use a computer that looks and acts like no computer you've ever seen. There is no keyboard or screen. Code designed for a normal computer is useless. The...

Who

Billions of objects ranging from smartphones and buildings, to machine parts and medical devices, to furniture and office supplies — any object that has a need to communicate with or sense other...

Wearable technologies are exploding in popularity in both the consumer and research spaces, but most of the electronic sensors that detect and transmit data from wearables are made of hard,...

In 1977, the National Renewable Energy Laboratory (NREL, Golden, CO) started as the Solar Energy Research Institute (SERI), spurred by national concern during the 1973 oil embargo that caused long lines...

To further develop semiconductor technology, the field of molecular electronics is seeking to manufacture circuit components from individual molecules instead of silicon. Because of...

The challenge of miniaturizing devices and systems is also achieving a broader dynamic range of detection for small signals such as sound, vibration, and radio...

Over the past few years, deep learning algorithms have proven to be highly successful in solving complex cognitive tasks such as controlling self-driving cars and language...

Data Acquisition System

The SLICE IP68 data acquisition system from DTS, Seal Beach, CA, measures physical signals in extreme test environments. It can embed in most test articles, and the rugged...

A battery pack is only as strong as its weakest cell. As battery packs become larger and more integral to the stable operation of devices and systems, the need to monitor battery dependability and performance...

The ability to measure the electronic conductivity of battery film coatings is a pressing need in the battery industry; however, these measurements can...

Extremely fine porous structures with tiny holes — resembling a kind of sponge at the nano level — can be generated in semiconductors. A method was developed for the controlled manufacture...

When it comes to the “smell test,” the nose isn't always the best judge of food quality. Now in a study appearing in ACS’ journal Nano Letters, scientists...

Laser diodes are one of a number of different types of electronic devices that generate heat during normal operation. Some power applied to such devices is lost as heat energy. To ensure stable...

Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides. Because the printing approach can also fabricate...

UCLA scientists and engineers have developed a new process for assembling semiconductor devices. The advance could lead to much more...

Replacing traditional computer chip components with light-based counterparts will eventually make electronic devices faster due to the wide bandwidth of light. Because...

Transistors, the tiny switches that form the bedrock of modern computing—billions of them — route electrical signals around inside the circuitry of our devices....

Silver nanowires have drawn significant interest in recent years for use in many applications ranging from prosthetic devices to wearable health sensors due to their flexibility,...

An increase in computing performance has been achieved by squeezing ever more transistors into a tighter space on microchips. This downsizing has also meant packing the wiring within...

NASA Marshall Space Flight Center has developed a numerically controlled grinding tool that eliminates undesirable periodic variations in surface contours in optical and other surfaces — such as mid-spatial...

NASA Ames Research Center has developed an innovative built-in temperature sensing method for micro-heaters. The temperature sensing of chip-based microheaters is conventionally done with...
