Injecting electrons jolts 2-D structure into new atomic pattern

Wed, 2017-10-11 22:47
The same electrostatic charge that can make hair stand on end and attach balloons to clothing could be an efficient way to drive atomically thin electronic memory devices of the future, according to a new study. Scientists have found a way to reversibly change the atomic structure of a 2-D material by injecting it with electrons. The process uses far less energy than current methods for changing the configuration of a material's structure.

Flexible sensors can detect movement in GI tract

Tue, 2017-10-10 23:09
A flexible ingestible sensor has been devised that could help doctors to diagnose problems caused by a slowdown of food flowing through the digestive tract. The sensors could also be used to detect food pressing on the stomach, helping doctors to monitor food intake by patients being treated for obesity.

Building a barrier against oxidation

Tue, 2017-10-10 01:41
Chemically stabilizing atomically flat materials improves their potential for commercial application, report scientists.

Novel circuit design boosts wearable thermoelectric generators

Mon, 2017-10-09 19:03
Using flexible conducting polymers and novel circuitry patterns printed on paper, researchers have demonstrated proof-of-concept wearable thermoelectric generators that can harvest energy from body heat to power simple biosensors for measuring heart rate, respiration or other factors.

Engineers invent breakthrough millimeter-wave circulator IC

Fri, 2017-10-06 18:29
Researchers continue to break new ground in developing magnet-free non-reciprocal components in modern semiconductor processes. They have built the first magnet-free non-reciprocal circulator on a silicon chip that operates at millimeter-wave frequencies, enabling circulators to be built in conventional semiconductor chips and operate at millimeter-wave frequencies, enabling full-duplex or two-way wireless.

Paper-based supercapacitor uses metal nanoparticles to boost energy density

Thu, 2017-10-05 21:40
Using a simple layer-by-layer coating technique, researchers have developed a paper-based flexible supercapacitor that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities -- and the best performance so far in a textile-based supercapacitor.

Superconductivity found in thin films of titanium oxide

Mon, 2017-10-02 20:57
Many of us are familiar with titanium dioxide, a whitener commonly used in sunscreens and paints such as the white lines seen on tennis courts. Less well known are other higher titanium oxides -- those with a higher number of titanium and oxygen atoms than TiO -- that are now the subject of intensifying research due to their potential use in next-generation electronic devices.

A sea of spinning electrons

Mon, 2017-10-02 18:18
Picture two schools of fish swimming in clockwise and counterclockwise circles. It's enough to make your head spin, and now scientists have discovered the 'chiral spin mode' -- a sea of electrons spinning in opposing circles.

MRIs are safe for patients with wide variety of pacemakers, defibrillators, study shows

Fri, 2017-09-29 19:03
Magnetic resonance imaging appears to be safe for patients with cardiac implantable electronic devices, even for chest imaging, according to a new study.

Flexible new platform for high-performance electronics

Thu, 2017-09-28 23:51
A team of engineers has created the most functional flexible transistor in the world -- and with it, a fast, simple and inexpensive fabrication process that's easily scalable to the commercial level. It's an advance that could open the door to an increasingly interconnected world, enabling manufacturers to add 'smart,' wireless capabilities to any number of large or small products or objects -- like wearable sensors and computers for people and animals -- that curve, bend, stretch and move.

Biodegradable microsensors for food monitoring

Thu, 2017-09-28 19:12
A new generation of microsensors could provide the vital link between food products and the Internet of Things. Researchers have developed an ultra-thin temperature sensor that is both biocompatible and biodegradable.

Band gaps, made to order

Thu, 2017-09-28 01:50
Engineers have created atomically thin superlattice materials with precision.
