Stretchable, Rubbery Semiconductors

Researchers have created stretchable, rubbery semiconductors including rubbery integrated electronics, logic circuits, and arrayed sensory skins fully based on rubber materials. The semiconductors have...

Additive manufacturing, or 3D printing, is a rapidly growing field in which solid objects can be produced layer-by-layer. This...

Anyone who skis, wears glasses, uses a camera, or drives a car is familiar with the problem: Coming into a humid environment from the cold causes eyewear, camera lenses, or windshields to...

Novel Techniques Trick Object Detection Systems

New adversarial techniques developed by engineers at Southwest Research Institute can make objects “invisible” to image detection systems that use deep-learning algorithms. These techniques...

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many...

3D Printer Uses Rays of Light to Shape Objects

Most 3D printers, including light-based techniques, build up 3D objects layer by layer. This leads to a “stair-step” effect along the edges. They also have difficulties creating flexible...

Unwanted porosity is typical to many manufacturing processes — from traditional casting to additive manufacturing (3D printing) — and is difficult to avoid entirely....

Method Shrinks Objects to the Nanoscale

Existing techniques for creating nano-structures are limited in what they can accomplish. Etching patterns onto a surface with light can produce 2D nano-structures but doesn’t work for 3D structures....

A team of bioengineers supported through a Small Business Innovation Research grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) has...

A Northwestern University research team has developed tiny optical elements from metal nanoparticles and a polymer that one day could replace traditional refractive...

Researchers at the University of Houston have created an inexpensive system that can detect lead in tap water at levels commonly accepted as dangerous, using a lens made with an...

Transparent, Self-Healing Electronic Skin

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.

Along with intensity and color, polarization is a property of light that can provide useful information for scene analysis; however, the human eye and most cameras cannot detect...

The Teletenna — a Hybrid Telescope Antenna System

Innovators at NASA’s Glenn Research Center have developed a hybrid telescope antenna system — Teletenna — to deliver high-data-rate communication over great distances. Teletenna has...

Ordinary WiFi can easily detect weapons, bombs, and explosive chemicals in bags at museums, stadiums, theme parks, schools, and other public venues using a low-cost suspicious...

Virtual Test Laboratory

The mechanical properties of sheet metal materials are directional. Their deformation behavior and their strength differ significantly depending on the viewing direction; for example, in the direction of rolling, or...

Sponsored by the Office of Naval Research's (ONR) TechSolutions program, the Flashing Light to Text Converter (FLTC) features a camera that can be mounted atop a signal...

New Fast, Economical Bioimaging Technique

Researchers at Rensselaer Poytechnic Institute (RPI) have developed a new approach to optical imaging that makes it possible to quickly and economically monitor multiple molecular interactions in a...

Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens that is essentially a flat,...

Outsourcing machine learning is a rising trend in industry. Major tech firms have launched cloud platforms that conduct computation-heavy tasks, such as running data through a convolutional...

Optimal Computational Vision Pipeline (OCVP)

Optimal Computational Vision Pipeline (OCVP) software uses a novel algorithm that allows overlapping point clouds obtained from sensors with displaced position and orientation to be fused together in a common coordinate system with a rigorously linear solution for position and orientation parameters;...

Researchers at the National Institute of Biomedical Imaging and Bioengineering (NBIB) have created a novel, low-cost biosensor to detect Human Epidermal...

Researchers have developed an imaging technique that uses a tiny, super sharp needle to nudge a single nanoparticle into different orientations and capture 2-D images to help...

It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials,...

Precision Low-Speed Motor Controller

Innovators at NASA Johnson Space Center have developed a method for controlling precise motion of a brushless DC (BLDC) motor using relatively inexpensive components. Precision motors are usually quite expensive and inefficient when operating at slow speeds. Current motors are only capable of operating at...

Numerous devices in everyday life use computerized cameras to identify objects — think of automated teller machines that can “read” handwritten dollar amounts when...

Engineers at Duke University have developed a way to extract a sequence of images from light scattered through a mostly opaque material — or even off a wall — from one long...

A new method of X-ray scanning will allow for the visualization of many more biological molecules, providing critical information about what is inside molecules to scientists...
