Accurately measuring semiconductor properties of materials in small volumes helps engineers determine the range of applications for which these materials may be suitable in the...

Innovators at NASA’s Glenn Research Center have developed a new means of avoiding and mitigating icing events for aircraft flying above 14,000 feet, dramatically improving aviation...

There's an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can't see. But infrared cameras can pick up this light emitted as...

Silicon is a naturally occurring material commonly used as a semiconductor in electronic devices; however, researchers have exhausted the potential of devices with semiconductors made...

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...

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...

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...

The traditional approach for wireless sensors involves interrogators that communicate with each other (i.e., the two boxes “talk” to each other). In contrast, surface acoustic wave...

GPS signals do not penetrate very deeply or at all in water, soil, or building walls, and therefore can’t be used by submarines or in underground activities such as surveying mines. GPS also...

Innovators at NASA’s Glenn Research Center have developed a hybrid telescope antenna system — Teletenna — to deliver high-data-rate communication over great distances. Teletenna has...

Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging, and Light Detection and Ranging (LIDAR) systems. In the...

Researchers have developed a prototype miniature medical device that could ultimately be used in smart pills to diagnose and treat diseases. A key to the new technology is that its location can be precisely...

In traditional hardwired avionics systems, sensor integration requires installation of literally tons of physical cable that significantly increases vehicle weight and the...

Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains...

Most naturally occurring materials have a disordered atomic structure that interferes with the propagation of both sound and electromagnetic waves. When the waves come into contact with these...

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...

For wireless networks that share time-sensitive information on the fly, it's not enough to transmit data quickly: that data also needs to be fresh. Consider the many sensors in your car. While it may...

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...
