Briefs: Software
Most of us know optical lenses as curved, transparent pieces of plastic or glass, designed to focus light for microscopes, spectacles, cameras, and more. For the most part, a lens’...
Briefs: Energy
Very thin nylon films were created that can be used in electronic memory components. The films are several hundreds of times thinner than a human hair and could be used in bendable electronic...
Briefs: Mechanical & Fluid Systems
Between walking and running, human gaits can cover a wide range of speeds; for example, at low speeds, the metabolic rate of walking is lower than that of running in a slow jog. The...

Neural Lander Uses AI to Land Drones Smoothly
Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often...
Briefs: Aerospace
Researchers at NASA’s Armstrong Flight Research Center are pioneering shape-sensing technologies that seek to maximize structural integrity and efficiency. A new and...
Briefs: Mechanical & Fluid Systems
A high-sensitivity and low-noise MEMS accelerometer was developed using multi-layer metal structures composed of multiple metal layers. The accelerometer achieves 1 μG level resolution that has...
Briefs: Sensors/Data Acquisition
Different instruments are needed to study the interaction of contact surfaces at different length scales. Tribometers measure the coefficient of friction but they cannot...
Briefs: Test & Measurement
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...

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: Electronics & Computers
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: Test & Measurement
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: Sensors/Data Acquisition
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: Electronics & Computers
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: Photonics/Optics
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...

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: Robotics, Automation & Control
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: Photonics/Optics
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,...
