A device and method have been developed to conduct compression and tensile tests on soft materials such as flocculated sediments, biopolymers, biological materials, and food stuffs. The device...

The measurement of mechanical behavior in very small samples whose dimensions are on the order of microns and below can offer advantages over conventional macroscopic testing in many instances. Motivations for investigating...

Artificial intelligence (AI) has been used to teach wireless devices to sense people's postures and movement, even from the other side of a wall. RF-Pose uses a neural network to analyze...

Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance...

A next-generation X-ray beamline now operating at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) brings together a unique set of capabilities to measure the...

Optoelectronic engineers in China and Hong Kong have manufactured a special type of liquid crystal display (LCD) that is paper-thin, flexible, light, and tough. With this, a daily...

Today's crop breeders are trying to boost yields while preparing plants to withstand severe weather and changing climates. To succeed, they must locate the genes for high-yielding, hardy traits in crop...

Currently, concussion is measured by the symptoms someone experiences, but it is difficult to know what is happening in the brain in any one person. To address this problem, a portable brain imaging system was...

Today's glass-based lenses are bulky and resist miniaturization. To address the problem, two different imaging methods — a type of lens designed for nanoscale interaction with lightwaves, and robust...

Positional sensors have applications where a very accurate measurement of position is needed over a limited range. One example of such an application is in manipulation of a...

A limitation of today's ultrasound devices is that they are difficult to use on objects that don't have perfectly flat surfaces. Conventional ultrasound probes have...

The wetting behavior of a liquid on a solid surface is a phenomenon of significant practical importance. The angle of liquid-to-solid contact is important in areas such as adhesion,...

A material was developed for nuclear radiation detection that could provide a significantly less expensive alternative to the detectors now in commercial use. Specifically, the high-performance material is...
