Hydrogels that combine the integrated attributes of being adhesive, self-healable, deformable, and conductive show great promise for next-generation soft robotic/energy/electronic applications. Herein, we reported a dual-network polyacrylamide (PAAM)/poly(acrylic acid) (PAA)/graphene (GR)/poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) (MAGP) hydrogel composed dual-cross-linked PAAM PAA as well PEDOT:PSS GR conducting component combines these features. A wearable strain sensor is fabricated by sandwiching MAGP hydrogels between two dielectric carbon nanotubes (CNTs)/poly(dimethylsiloxane) (PDMS) layers, which can be utilized to monitor delicate vigorous human motion. In addition, hydrogel-based act deformable triboelectric nanogenerator (D-TENG) harvesting mechanical energy. The D-TENG demonstrates peak output voltage current 141 V 0.8 μA, respectively. could easily light 52 yellow-light-emitting diodes (LEDs) simultaneously demonstrated capability power small electronics, such hygrometer thermometer. This work provides potential approach development energy sources self-powered sensors.
