It has been known since the early 1960s that hexagonal sampling is the optimal sampling approach for isotropically band-limited images, providing a 13.4% improvement in sampling efficiency over...

Researchers developed a wearable, disposable respiration monitor that provides high-fidelity readings on a continuous basis. It's designed to help children with asthma and cystic...

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...

Bioengineers have cleared a major hurdle on the path to 3D-printing replacement organs with a new technique for bioprinting tissues. It allows scientists to create entangled vascular networks...

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...

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 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...

Aircraft currently fly based on coarse estimations of environment and aircraft state. Real-time measurements are traditionally restricted to laboratory environments (e.g. wind tunnel) due to the size and...

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...

A robot is being developed that tracks facial movements to perform human tasks. The robot resembles large, squiggly arms holding tiny cameras. Sitting in a rolling office chair across from one of the arms, the robot's...

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...

Experimental photonic switches developed at UC Berkeley have shown promise toward the goal of fully optical, high-capacity switching for...

With the aim of bringing more human-like reasoning to autonomous vehicles, MIT researchers have created a system that uses only simple maps and visual data to enable driverless cars...

There are many different types of 3D printing technologies. The most familiar — inkjet — has been around for some 20 years. But until now, it has been difficult to...

For the millions of people every year who have or need medical devices implanted, an advancement in 3D printing technology could enable significantly quicker...

Microchannels fabricated into a silicon-Pyrex wafer with a diameter of 75 m and total channel length of 40, 60, 80, or 100 mm — characterized by specialized microbeads...
