Washable Sensor Can Be Woven Into Materials

摘要

Alow-cost sensor was developed that can be interlaced into textiles and composite materials, paving the way for smart clothing that can monitor human movement. The embedded microscopic sensor is able to recognize local motion through the stretching of woven yarns treated with graphene nanoplatelets that can read the body's activity. The device uses a phenomenon called piezoresistivity — an electromechanical response of a material when it is under strain. These tiny sensors have shown great promise in detecting human movements and can be used for heart rate monitoring or temperature control.
