In this compendium of recent articles from the editors of Aerospace & Defense Technology and Tech Briefs, read about how high-frequency electronics advances are enabling new applications in space communications, aviation, the military and more.
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...
Dr. Sultana won funding to advance a nanomaterial-based detector platform that can sense environmental parameters from minute concentrations of target gases and vapors, to atmospheric pressure and temperature, and then transmit that data via a wireless antenna — all from the same 3...
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...
Small unmanned aircraft systems (UAS), also known as micro air vehicles, are promising tools for a variety of military and commercial applications. Some small UAS have flexible wings and are lightweight, making them back-packable and easy to deploy. Most UAS that are...
Lightweighting design is an extensively explored and utilized concept in many industries, especially in aerospace applications, and is associated with the green aviation concept. 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...
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...

The Create the Future Design Contest was launched in 2002 to help stimulate and reward engineering innovation. In the past 16 years, the annual contest has drawn more than 13,000 product...
The Sitrans TH320/420 and TR320/420 WirelessHART (Highway Addressable Remote Transducer Protocol) temperature transmitters from Siemens, Erlangen, Germany, are available for a...
Over the past 60 years, NASA scientists and engineers have developed many advanced technologies and processes. But NASA has also partnered with industry, using commercially available products to complete its missions. Here, some of those companies join NASA in celebrating these collaborative successes.
By integrating the design of antenna and electronics, researchers have boosted the energy and spectrum efficiency for a new class of millimeter wave transmitters, allowing...
NASA's Langley Research Center has developed a SansEC Sensor technology for use with aerospace fuel delivery systems. The SansEC technology is a...
Microwave antennas deployed for spaceborne radiometers are diffraction-limited, with typical beam efficiency of about 90%, and provide relatively poor selectivity against radiation from celestial bodies (Moon, Sun, galaxy) when they...
NASA Glenn’s cup cylindrical waveguide antenna (CCWA) is a short backfire microwave antenna capable of simultaneously supporting the transmission or reception of two distinct signals having opposite...
Non-Linear Junction Detection is a well-known technique for detecting electronics that utilize semiconductor (solid-state) junctions. The current state of the art for finding hidden electronics — such as electronic eavesdropping devices — using this technology has a maximum range of about 2 m, and more...
NASA’s Marshall Space Flight Center is building a small CubeSat that uses an 85-m2 solar sail deployed from a central location to capture the push of photons...
This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. To learn more about each technology, see the contact information provided for that...
Sensors have a key role in industrial production. For example, they can be used for quality and process monitoring or condition-based maintenance. The range of applications is large and is evolving even further, largely due to the increasing use of self-powered wireless sensors...
Scientists have developed a demonstrator that powers active implants wirelessly via ultrasound. Ultrasound waves have a broader range in the body, and they penetrate the implant’s metal casing more easily than electromagnetic waves. The ultrasound waves are also capable of bidirectional...
