Lining MOF pockets to detect noxious gases

A porous material with tailor-made pockets stitched into its structure is a promising material for sensing noxious gases. A thin film of the material, coated onto an electrode, formed an electronic sensor that could detect ...

Touch-sensitive avatar-robotic arm based on real-time haptics

Researchers at Keio University's Haptics Research Center have developed a 'real-time-avatar-robotic arm' that transmits sound, vision, and highly sensitive feelings of touch to remotely located users. This innovative touch ...

Graphene enables high-speed electronics on flexible materials

A flexible detector for terahertz frequencies (1000 gigahertz) has been developed by Chalmers researchers using graphene transistors on plastic substrates. It is the first of its kind, and can extend the use of terahertz ...

Graphene sensors detect HIV DNA

Leiden and Jülich researchers discovered an elegant and simple approach to improve the sensitivity of graphene biosensors. These so-called 'next generation graphene electronic biochemical sensor devices' are able to detect ...

A fashionable chemical and biological threat detector-on-a-ring

Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They're even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors ...

Flexible sensors can detect movement in GI tract

Researchers at MIT and Brigham and Women's Hospital have built a flexible sensor that can be rolled up and swallowed. Upon ingestion, the sensor adheres to the stomach wall or intestinal lining, where it can measure the rhythmic ...
