Biocompatible, self-wrinkled, antifreezing and stretchable hydrogel-based wearable sensor with PEDOT:sulfonated lignin as conductive materials

Gel-based strain sensors have great potential in the fields of motion detection and real-time healthcare. Nevertheless, the relatively low strain sensitivity and inferior anti-freezing property limit the utilization of these sensors. In this work, a novel multifunctional organohydrogel sensor was developed based on a poly (acrylic acid) (PAA) skeleton with poly (3,4-ethylenedioxythiophene): sulfonated lignin (PEDOT:SL) as the conductive material...
