Professor Hopkins and University of Virginia colleagues — in collaboration with materials scientists at Penn State, the University of...
Briefs: Materials
Current density is the amount of electrical current per cross-sectional area at a given point. As transistors in integrated circuits become smaller and smaller, they need higher and higher...
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 few...
Briefs: Photonics/Optics
MIT researchers have designed an optical filter on a chip that can process optical signals from across an extremely wide spectrum of light at once, something never before...
Briefs: Medical
With novel optoelectronic chips and a new partnership with a top silicon-chip manufacturer, MIT spinout Ayar Labs aims to increase speed and reduce energy consumption in computing, starting with...

The benefits of NASA's space exploration efforts are not limited to the cosmos. NASA technologies provide innovative solutions for people around the world. NASA missions have generated thousands of spinoffs —...
Articles: Electronics & Computers
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 components...
Briefs: Photonics/Optics
Researchers have 3D-printed an array of light receptors on a hemispherical surface. This discovery could lead to a “bionic eye” that could someday help blind people see or sighted...
Briefs: Electronics & Computers
Photons, or units of light, are faster than electrons and could, therefore, process information faster from smaller chip structures. A switch was designed that bypasses a...
Briefs: Communications
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 material...
Briefs: Electronics & Computers
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...

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 objects.
Briefs: Automotive
The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...
Briefs: Sensors/Data Acquisition
It is often desirable to sense the angular position of a rotating part. Numerous kinds of rotation sensors have been developed over the years; one type is a capacitive sensor, where a capacitance...
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: Manufacturing & Prototyping
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,...
