Abstract Ion‐gels, with inherent flexibility, tunable conductivity, and multi‐stimulus response, have attracted significant attention in flexible/wearable electronics. However, the design of ion‐gels that exhibit both strength toughness is challenging. In this study, a novel ion‐gel proposed mimics hierarchical meshing structure leaves combination ion hybridization. Polyacrylamide (PAM) incorporated TEMPO oxidized cellulose nanofibers (TOCNFs) clusters by situ polymerization, generating hydrogel micro/nanoscale entangled networks. Replacement water metal halide ionic liquid ([BMIm]Zn x Cl y ) resulted formation an hybrid network supramolecular interactions. The integration PAM/TOCNF polymer [BMIm]Zn high (5.9 MPa), (22 MJ m −3 ), enhanced elastic modulus (30 MPa) combined non‐flammability, heat cold resistance. While having fast responsiveness (36 ms) sensing signal stability power supply even at 4000 cycle collisions. Stable output (200 °C) /sub‐zero temperatures. strategy offers new approach to material
