Scientists have taken inspiration from underwater invertebrates like jellyfish to create an electronic skin with similar functionality. Like a jellyfish, the electronic skin is transparent, stretchable, touch-sensitive, and self-healing in aquatic environments.

Researchers have developed a new technique that assesses radiation exposure in about an hour using an insulator material found in most modern electronics. The technique can be used to triage medical cases in the event of a radiological disaster.

Growing demand for electric vehicles and more sustainable forms of transport means finding new forms of energy storage such as batteries, supercapacitors, and fuel cells. Currently, a major challenge facing the industry is the poor performance quality of rechargeable batteries, which often lose...

NASA’s Glenn Research Center has devised an efficient new method of combining primary and secondary signals with minimal loss and noise. With its ability to reduce system noise, this novel signal combiner delivers the best opportunity to receive a desired signal not easily distinguished from background...

In many applications, such as remote sensing of atmospheric trace gases, monochromatic radiation with multiple discrete wavelengths is required. To date, there no instrument or technique that measures the wavelength jitters and fluctuations in real time.

Large-scale, high-performance computing — supercomputing — is essential to solving both complex and large questions. But storage platforms essential for these advanced computer systems have been stuck in a rigid framework that required users to either choose between customization of...

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 currently...

Distributed systems have become an integral part of safety-critical computing applications, necessitating system designs that incorporate complex fault-tolerant resource management functions to provide globally coordinated operations with ultra-reliability. As a result, robust...
