Abstract With the development of flexible wearable devices, conductive hydrogels have attracted widespread attention due to their unique properties. However, traditional often suffer from poor mechanical properties and environmental stability, greatly limiting application areas. Herein, a dynamic hydrophobically associated organo‐hydrogel network, which is composed polymer chain backbone (acrylamide lauryl methacrylate), dispersant (sodium dodecyl sulfate), filler (lithium bis(trifluoromethyl)sulfonimide), crosslinker (containing imine bonds) constructed. Then, through solvent replacement strategy glycerol, organo‐hydrogels are obtained with excellent (1.21 MPa strength, 12.87 MJ m −3 toughness, 3501% ultra‐stretching), outstanding stability (work stably in wide range −20 60 °C), room‐temperature self‐healing ability (self‐healing efficiency over 90%). Based on these performances, they used as working electrode triboelectric nanogenerators, endows nanogenerators an output voltage 127 V, power density 205 mW −2 , maintain stable 10 000 cycles. A self‐powered sensor also constructed, can realize function material recognition assistance machine learning. This work will provide new ideas for novel sensors.
