An anti-freezing/drying, adhesive and self-healing motion sensor with humidity-enhanced conductivity

Flexible gels have shown great potential in electronic sensors, but their conductivity may decrease or even disappear after long-term or extreme temperature use. Here, a new class of conductive organohydrogel sensors was fabricated with multipurpose adhesion, anti-freezing/drying, excellent humidity-enhanced conductivity, and self-healing properties. By employing the appropriate glycerol/water ratio, the organohydrogel sensor can be used either under low (-30 degrees C) or high (60 degrees C) temperature, featuring for catching water from the environment to enhance the conductivity. This work hold promises for the fabrication of high-performance sensing material with multi-functional sensing and synergistic properties.
