Researchers at the Georgia Institute of Technology have made the first skin-like sensor array from individual-nanowire light-emitting diodes that can convert touch directly into light signals. The new device, which works thanks to the piezophototronic effect, appears to be more sensitive to touch than even human skin. It might be ideal in robotics applications, in next-generation touchscreen pads, for improved human-machine interfaces, biological imaging and optical microelectromechanical systems (MEMS) to name but a few…….
