Self-powered MC-TENG device aims to foil forest fires

Researchers have developed MC-TENG, a remote forest fire detection and alarm system powered by the movement of the trees. The new device generates electrical power by harvesting energy from the sporadic movement of the tree branches from which it hangs (Image: MSU) MC-TENG Developed at Michigan State University (MSU), MC-TENG – multi-layered cylindrical triboelectric nanogenerator … Continue reading Self-powered MC-TENG device aims to foil forest fires

Shapes revealed with stimulation of visual cortex

Researchers in the US have developed a method of stimulating the visual cortex and restoring a degree of vision for people who are blind. This figure illustrates how dynamic stimulation to the visual cortex enables participants to ‘see’ shapes (Image: Beauchamp et al./Cell) For many adults, blindness often results from damage to the eyes or … Continue reading Shapes revealed with stimulation of visual cortex

Make UK draw up three-point plan for recovery

Make UK is calling on government to extend the furlough scheme for manufacturers so that they can scale up operations once Covid-19 restrictions ease. This is one part of a three-point plan drawn up by the manufacturers association intended to help the sector recover following the Covid-19 crisis. Other measures (see below) include boosting economic … Continue reading Make UK draw up three-point plan for recovery

Stabilised halide perovskites promise better solar panels

Researchers have inhibited the ion movement in halide perovskites, an advance that could unlock their use for more efficient solar panels as well as electronic devices. Adding a bulky molecule to the surface of a perovskite might finally make the material stable enough for incorporating into solar panels (Purdue University illustration/Enzheng Shi) As well as … Continue reading Stabilised halide perovskites promise better solar panels

Blind source separation and AI offer clear communications

Blind source separation technology and AI are completely cross-compatible with each other when it comes to noise reduction, says Dave Betts, chief science officer at AudioTelligence. Open-plan offices often come under fire for being noisy and disruptive – making it difficult for workers to concentrate or join conference calls. Requests to work remotely tend to … Continue reading Blind source separation and AI offer clear communications
