Science Daily  August 2, 2019 A team of researchers in the US (UT Houston, University of Colorado) has developed a multifunctional soft stretchable HMI device based on sol-gel-on-polymer–processed indium zinc oxide (IZO) semiconductor nanomembrane electronics. Stretchable resistive random-access memory (ReRAM) for data storage components as well as field-effect transistors for interfacing and switching circuits, temperature, strain, and ultraviolet sensors are developed. The devices are constructed in an ultrathin (3 to 4 μm) and narrow meandering serpentine-shaped open-mesh configuration, which renders their mechanical stretchability (stable operation up to 30%). It collects signals from the human muscle, directly guides the robot, and […]
