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...

Artificial intelligence (AI) has been used to teach wireless devices to sense people's postures and movement, even from the other side of a wall. RF-Pose uses a neural network to analyze...

Today, more than 8 billion devices are connected around the world, including medical devices, wearables, vehicles, and smart household and city technologies. Those devices are vulnerable to...

First responders often have trouble communicating with each other in emergencies. They may use different types of radios, they may be working in rural areas lacking wireless coverage, or they may be...

Researchers at NASA's Marshall Space Flight Center have devised a method for the creation of crystal-free non-oxide optical fiber preforms. Non-oxide fiber optics are extensively used in...

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's Langley Research Center has developed a SansEC Sensor technology for use with aerospace fuel delivery systems. The SansEC technology is a...

Demands for improved computer processing power have led researchers to explore both new processes and other materials beyond silicon to produce electronic components....

Power electronics used for routing, control, and conversion of electrical power traditionally utilize silicon semiconductors. These systems tend to be bulky, require active cooling, and are inadequate for...

Vanadium dioxide’s unique properties make it ideally suited for outperforming silicon and giving rise to a new generation of low-power electronic devices. This compound can...

Microphones, from those in smartphones to hearing aids, are built specifically to hear the human voice — humans can’t hear at levels higher than 20 kHz, and microphones max out at...
