A technology uses a combination of WiFi signals and accelerometer technology to track devices in near-real-time.

A novel approach was developed to improve communications range and allow for covert behavior using a team of robots for future multi-domain operations. Specifically, researchers...

To investigate oceans, researchers aim to build a submerged network of interconnected sensors that sends data to the surface. Supplying constant power to scores of sensors designed to stay for long...

Although Radio Frequency Identification (RFID) technology is being used widely for pallet and box-level tracking in the commercial sector, significant technology gaps remain for tracking dense quantities at the item...

Contact lenses that can monitor the wearer’s health and correct eyesight use embedded electronics. These, and other curved devices such as solar cells and electronics, could be...

A new wireless transceiver was developed that boosts radio frequencies into 100-gigahertz territory, which is quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications...

Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create images of organs and tissues in the human body, helping doctors diagnose potential problems or diseases. Doctors use MRI to...

Today’s cellular networks and Wi-Fi systems rely on microwave radiation to carry data but the demand for more bandwidth is quickly becoming more than microwaves can handle. That has...

Since 1998, almost 2,000 shoebox-sized satellites known as CubeSats have been launched into space. Due to their small frame and the fact that they can be made from off-the-shelf...

Scientists of Karlsruhe Institute of Technology (KIT) and École Poly-technique Fédérale de Lausanne (EPFL) have reported that they achieved the fastest distance measurement attained so...

A pocket-sized antenna was developed that could enable mobile communication in situations where conventional radios don’t work such as underwater, through the ground, and over very...

Researchers have created a fabric that automatically regulates the amount of heat that passes through, depending on conditions; for example, when conditions are warm and moist — such as those of a...

Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to...

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...
