Fluid could provide a new source of information for routine diagnostic testing.
Briefs: Design
Using state-of-the-art indium phosphide transistors and a basic computer and mirrors, researchers were able to produce images of concealed bodies.
Briefs: Sensors/Data Acquisition
Incorporating new green-light absorbing transparent organic photodetectors into organic-silicon hybrid image sensors could be useful for applications such as light-based heart-rate monitoring, fingerprint recognition and devices that detect the presence of nearby objects
Briefs: Robotics, Automation & Control
Made from 3D graphene foam, the sensors use a piezoresistive approach, meaning when the material is put under pressure it dynamically changes its electric resistance, easily detecting and adapting to the range of pressure required, from light to heavy.
Briefs: Materials
An open-access study in Advanced Science outlines the process by which Preston and lead author Faye Yap harnessed a spider’s physiology in a first step toward a novel area of research they call “necrobotics.”
Briefs: Design
Biomimetics is one of the most important robotic research methods which can improve the kinematic performance of robots by imitating the structure and behavior of natural organisms.
Briefs: Motion Control
Researchers have taken inspiration from origami to create inflatable structures that can bend, twist, and move in complex, distinct ways from a single source of pressure.
Briefs: Data Acquisition
The sensor works by detecting variations in microgravity using the principles of quantum physics, which is based on manipulating nature at the sub-molecular level.
Briefs: Data Acquisition
Some wearable devices are already capable of measuring pulse rates or temperatures, but this team’s method would allow the technology to sense biomarkers related to metabolic disorders, like heart disease or diabetes.
Briefs: Energy
The biofilm has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.
Briefs: Electronics & Computers
The OLEDs are fabricated onto temporary tattoo paper and transferred to a new surface by being pressed onto it and dabbed with water.
Briefs: Materials
The technology allows for higher surface conductivity, improved impedance control, expanded design and application potential, and greater choice of materials for optimized performance.
Briefs: Lighting Technology
But they’re not yet small enough to compete in computing and other applications where electric circuits continue to reign.
Briefs: Electronics & Computers
To benchmark performance of printed sensors against the state of the art, NASA has developed a low-power flexible sensor platform.
Briefs: Photonics/Optics
The design produces a compact, efficient, long-lifetime laser transmitter as needed for use in space, while also having potential applications as an airborne or ground-based wind measurement tool.
Briefs: Imaging
A group of scientists led by the U.S. Department of Energy’s Argonne National Laboratory has created a new method for improving the resolution of hard X-ray nanotomography.
Briefs: Photonics/Optics
Enter the frequency comb, a Nobel Prize-winning device and the result of decades of research from NIST and others. The comb generates a billion pulses of light per second, which bounce back and forth inside an optical cavity.

Ultrathin Holographic Display
An ultrathin display for holographic images consists of a thin film of titanium filled with tiny holes that precisely correspond with each pixel in a liquid crystal display (LCD) panel.
Briefs: Communications
The new NIST instrument captures waves in action by relying on a device known as an optical interferometer.
Briefs: Medical
The device could transform public health officials’ ability to quickly detect and respond to the coronavirus — or the next pandemic.
Briefs: Connectivity
The sensor tags, which are embedded with a processor and memory bank for acquired data, are placed about the vehicle and stream data only when queried by a fixed-location RFID interrogator.
Briefs: Medical
The final product could make temperature measurements that are 10 times more precise than state-of-the-art techniques, acquired in one-tenth the time in a volume 10,000 times smaller.
Briefs: Medical
Unlike other tests, this test gives an estimate of viral load or the number of virus particles in a sample, which can help doctors monitor the progression of a COVID-19 infection and estimate how contagious a patient might be.
Briefs: Sensors/Data Acquisition
The innovation opens the door for faster and more affordable at-home medical testing.
Briefs: Sensors/Data Acquisition
Adding a flexible backing to this kind of brain-computer interface allows the device to more evenly conform to the brain’s complex curved surface and to more uniformly distribute the microneedles that pierce the cortex.
Briefs: Materials
One common limitation of AM has been that produced articles cannot be recycled without substantial energy costs.
Briefs: Materials
By incorporating a special type of plastic yarn and using heat to slightly melt it — a process called thermoforming — the researchers were able to greatly improve the precision of pressure sensors woven into multilayered knit textiles, which they call 3DKnITS.
Briefs: Test & Measurement
Cubic boron arsenide provides high mobility to both electrons and holes, and it has excellent thermal conductivity. It is, according to the researchers, the best semiconductor material ever found.
Briefs: Medical
Instead of surgically removing a sample of skin, sending it to a lab, and waiting several days for results, your dermatologist takes pictures of a suspicious-looking lesion and quickly produces a detailed, microscopic image of the skin. This could become routine in clinics.
