Long-term health monitoring of adults, babies and small children without concern for skin injury or allergic reactions is the aim of a project at Georgia Tech, which has produced a stretchy patch that can broadcast electrocardiogram (ECG), heart rate, respiratory rate and motion activity data. Connections are to gold skin-like electrodes through printed conductors that can stretch with the medical ...

It is possible to deposit metal tracks on soft surfaces including jelly, as has been proved by Iowa State University

Forget nets, attack drones, or lasers – Korean researchers have found a way to coax rogue drones out of the sky – at least, most of those flying on GPS autopilot. “This technology can safely guide a drone to a desired location without any sudden change in direction in emergency situations,” according to national research university KAIST. Spoof GPS signals ...

US researchers have used a supercomputer to discover a candidate for Pb-free perovskite solar cells – most solar perovskites contain Pb-halides, and are unstable in moist air. KBaTeBiO6 is the material, a bismuth-halide double perovskite that was the most promising of 30,000 candidate bismuth-containing oxides postulated by a team of engineers at Washington University in St Louis using data analytics and ...

QuaDRiGa 2.2, is a comprehensive update of the open-source radio channel model.

GaSb/AlAsSb ‘separate absorption and multiplication avalanche’ photodiodes (SAM-APDs) can be used to selectively detect high-energy electromagnetic x-ray and gamma-ray radiation, according to the University of California, Los Angeles. Its research team has built such detectors, that can observe well-defined X-ray and gamma-ray photo-peaks from an americium 241 source (1.55GBq) at up to 59.5keV with a full-width half-maximum of 1.283keV. In SAM-APDs, the ...

London start-up Slamcore has developed algorithms that it says could slash the costs of robotics navigation. Electronics Weekly reporter Alex McCarthy visited the company’s offices to find out more. EW saw a controlled demonstration of Slamcore’s simultaneous localisation and mapping (SLAM) technology. For autonomous robots performing tasks in dynamic environments, SLAM technology is described as a baseline consideration. It has ...

Georgia Tech is aiming at environmental monitoring, precision agriculture, and infrastructure maintenance with an aerial robot that trades speed for energy-efficiency. Called SlothBot, it is intended linger for months, hanging at height from a network of wires, measuring chemical concentrations or other parameters that can only be recorded by a long-term presence. Being wire-suspended allows the robot to move to ...

5G RailNext, a consortium led by Cisco which includes Soluis and Ampletime of London, Strathclyde University and Glasgow Council, has won a competition to see how 5G can best provide infotainment services across the Seoul Metro system (pictured). The project will deliver Augmented Reality (AR) and Mixed Reality (MR) content – including travel information, video streaming and gaming – through ...

Researchers demonstrate an amorphous SiC ring resonator with a Q of 1.6x105
