Self-repairable and recyclable self-powered human motion sensor with NIR/pH-responsive amplified Stretchable, Conductive, and Self-Healable hydrogel

A self-repairable and reusable self-powered electronic skin sensor is developed from NIR/pH-responsive polymer dot (PD) embedded hydrogel with amplified mechanical and electrochemical properties after self-healing. The pH/NIR-controlled mechanical, electrochemical and self-healing performance of the designed hydrogel is achieved by manipulating the hydrogen bond formation with tunable mobility from the PD components. The hydrogel formed at pH...
