Abstract The rapid advancement in attractive platforms such as biomedicine and human‐machine interaction has generated urgent demands for intelligent materials with high strength, flexibility, self‐healing capabilities. However, existing ability are challenged by a trade‐off between low elastic modulus, healing due to the inherent strength of noncovalent bonding. Here, drawing inspiration from human fibroblasts, monomer trapping synthesis strategy is presented based on dissociation reconfiguration amphiphilic ionic restrictors (7000‐times volume trapping) develop eutectogel. Benefiting nanoconfinement dynamic interfacial interactions, molecular chain backbone formed confined domains mechanically reinforced while preserving soft movement resulting eutectogels demonstrate superior mechanical properties (1799% 2753% higher tensile toughness than pure polymerized deep eutectic solvent), excellent efficiency (>90%), tangential modulus (0.367 MPa during working stage), sensitively monitor activities. This poised offer new perspective developing wearable electronics tailored body motion.

Zwitterionic hydrogels have gained prominence in flexible electronics for their biocompatibility. However, applications are hindered by weak mechanical strength and low conductivity. Herein, we proposed an innovative strategy fabricating multiscale cellulose-modified zwitterionic through electrostatic regulation. The employed poly(vinyl alcohol) [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide matrix, where the dispersion-aggregation architecture of anionic carboxymethyl cellulose sodium cationic polyethylenimine-modified nanocrystals (PEI@CNC) was precisely controlled via protons. Furthermore, were fabricated cyclic freezing-thawing process situ monomer polymerization. results demonstrate that incorporation PEI@CNC leads to synergistic enhancement properties ionic tensile conductivity DPCC-0.25 sample 8.4 times 2.2 those original hydrogel, respectively. This is attributed dynamic hydrogen bonding interactions porous network based on ionized cellulose. Moreover, hysteresis area tests at 100% strain negligible, indicating excellent elasticity. Its strain-sensing capability exhibits hysteresis-free resistive responses across 1%-400% strains with stable cyclability real-time accuracy.
