Briefs: Manufacturing & Prototyping

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

Feature Image
Briefs: Photonics/Optics

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....

Feature Image
Briefs: Electronics & Computers

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It...

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.

Briefs: Test & Measurement

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...

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

Feature Image
Briefs: Electronics & Computers

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...

Feature Image
Briefs: Medical

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,...

Feature Image
Briefs: Photonics/Optics

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

Feature Image
Briefs: Imaging

Detecting the nuances of nonverbal communication between individuals will allow robots to serve in social spaces, enabling them to perceive what people around them are doing, what moods they are...

Feature Image
Briefs: Materials

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...

Feature Image
Briefs: Imaging

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...

Feature Image
Briefs: Mechanical & Fluid Systems

Painting of surfaces having numerous facets and/or curved surfaces is a time-consuming process that requires the application of several coats (layers) of paint. Such surfaces are often found on...
