In the wake of recent developments that have reduced fan and jet noise contributions to overall jet-engine noise, aircraft designers are turning their attention toward reducing engine core...

Researchers at NASA’s Armstrong Flight Research Center are pioneering shape-sensing technologies that seek to maximize structural integrity and efficiency. A new and...

Different instruments are needed to study the interaction of contact surfaces at different length scales. Tribometers measure the coefficient of friction but they...

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...

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...

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...

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...

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...

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...

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...

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...

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...

Although smartphones and other consumer cameras are increasingly used for scientific applications, it's difficult to compare and combine data from different...

Suppose you have 10 taxis in Manhattan. What portion of the borough’s streets do they cover in a typical day?

Wearing a sensor-packed glove while handling a variety of objects, researchers compiled a dataset that enables an AI system to recognize objects through touch alone. The information...

NASA's Langley Research Center offers a novel lifting and precision positioning device with hybrid functional characteristics of both crane-type lifting devices and robotic manipulators. The design of the...

Interstitial fluid is clear, colorless, and similar to blood plasma. Continual sampling of important biomarkers in interstitial fluid could help monitor and diagnose many diseases and...

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...

A continuous-testing device was developed that samples sweat as effectively as blood but in a noninvasive way and over many hours. After examining the use of saliva, tears, and...

There is a need for high-volume material testing/qualification but industry and researchers are currently limited by commercially available testing devices. Most wear testers can only handle one...

In the polymer composites industry, cure cycles are typically developed from trial-and-error or a more effective processing science approach to reduce...

By capping liquids with graphene (an ultrathin sheet of pure carbon), researchers can easily image and analyze liquid interfaces and the surface of nanometer-scale objects...
