At the scale of bridges or buildings, the most important force that engineered structures need to deal with is gravity. But at the scale of microelectro-mechanical systems (MEMS) — devices like the...
Briefs: Energy
The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of...
Briefs: Mechanical & Fluid Systems
Robotics has traditionally focused on industrial applications in which robots require strength and precision to carry out repetitive tasks. These robots flourish in highly...
Briefs: Materials
Landing is stressful on a rocket’s legs because they must handle the force from the impact with the landing pad. One way to combat this is to build legs out of materials that absorb some of the...
Briefs: Electronics & Computers
Some organic materials cannot be utilized similarly to silicon semiconductors in optoelectronics. Whether in solar cells, light-emitting diodes, or in transistors, what is important is the bandgap, i.e. the...
Briefs: Electronics & Computers
Recently discovered two-dimensional (2D) materials with superlative properties have the potential to advance semiconductors but creating 2D devices with both good electrical contacts and...

Multi- and Wide-Band Single-Feed Patch Antenna
A novel patch antenna technology was developed that provides significant benefits to NASA satellite communication applications, offering a unique wide-band/multi-band operating capability. For other non-space applications, the antenna design also offers broadband capability with high gain for...
Briefs: Materials
Unlike water, liquid refrigerants and other fluids that have a low surface tension spread quickly into a sheet when they come into contact with a surface. For many industrial processes,...
Briefs: Robotics, Automation & Control
While different approaches have been used to create artificial muscles — including hydraulic systems, servomotors, shape-memory metals, and polymers that respond to stimuli — they all have limitations such as...

Virtual MIL-STD-1553B Remote Terminals
For complex boards with multiple FPGAs, each FPGA can implement its own remote terminal (RT) core and present itself logically to the bus as a remote terminal while sharing the RT’s hardware. This simplifies the design since commands and telemetry do not have to be distributed and collected by user logic;...

Antenna Near-Field Probe Station Scanner
Antenna characterization techniques are often expensive and time-consuming. NASA’s Glenn Research Center developed a highly versatile and automated system to perform characterization of single or multiple small circuit antennas, printed on-wafer or on other substrates, by measuring the antenna’s...

Self-Configurable Radio Receiver System and Method
A self-configurable radio receiver system was developed for relaying communication signals from multiple deep space assets. Most conventional radio receivers are hardwired to receive a specific type of signal and are incapable of receiving other types of signals without preconfiguration according...
Briefs: Sensors/Data Acquisition
A soft and conformable health monitor can broadcast electrocardiogram (ECG), heart rate, respiratory rate, and motion activity data as much as 15 meters to a portable recording device...
Briefs: Software
The Advanced Explosive Ordnance Disposal Robotic System (AEODRS) features a modular open systems architecture that enables the robot to be self-righting after a fall. The self-righting...
Briefs: Manufacturing & Prototyping
In the future, soft, animal-inspired robots may be safely deployed in difficult-to-access environments in which rigid robots cannot currently be used such as inside the human body or in spaces that are too...
Briefs: Sensors/Data Acquisition
A portable, stable, standards-quality radiation thermometer was invented that can measure temperatures between -50 °C (-58 °F) to 150 °C (302 °F). The corresponding infrared wavelengths...
Briefs: Test & Measurement
In order to qualify miniature springs, manufacturers of these systems rely on commercially available testers that are designed for large-scale springs (>0.5" diameter). Commercially available spring test...
Briefs: Materials
An electrochemical sensing system that significantly improves the ability to rapidly and accurately detect heavy metals in biological and environmental samples was developed. Using a simple blood sample...
Briefs: Communications
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...
Briefs: Imaging
Accurately detecting, locating, and quantifying leaks of methane — the main component of natural gas and a major fuel source worldwide — is critically important for both environmental and...
Briefs: Manufacturing & Prototyping
A 3D-printed polymer-based foam structure was developed that responds to the force of a shock wave to act as a oneway switch, a long sought-after goal in shock research. The...

Graphene Field Effect Transistors for Radiation Detection (GFET-RS)
NASA Goddard Space Flight Center developed novel transistor technology based on a single graphene layer coupled to a radiation absorber substrate. Unlike conventional charge-sensing detectors, the GFET-RS utilizes the sensitive dependence of graphene conductance on local change of...
Briefs: Test & Measurement
Adding fluoride to water has been common practice in a number of countries including the U.S. In low concentrations (below 1.5 mg/L), fluoride can help prevent tooth decay and...

Material for Faster Computer Memory
Scientists are studying bismuth ferrite (BFO) material that has the potential to store information much more efficiently than is currently possible. BFO could also be used in sensors, transducers, and other electronics.
Briefs: Propulsion
Microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body have been developed that also can treat tumors in the...
Briefs: RF & Microwave Electronics
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 parts,...
Briefs: Manufacturing & Prototyping
Researchers have created 3D-printed flexible mesh structures that can be controlled with applied magnetic fields while floating on water. The structures can grab small objects and carry water droplets, giving them...
Briefs: Data Acquisition
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 long...
