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.

In nature, animals can realize multimodal movements such as walking, climbing, and jumping through transformation in locomotor gaits or form for survival, which is highly desired untethered flexible actuators yet remains challenging. Here, we propose a robust self-healing actuator enabled by noncovalent assembled nanostructures with elaborate regulation of multistage responsive behaviors. Owing to the dynamic interfacial design between multiple components, stimulus be accurately delivered "light-heat-force release" pathway, endowing diverse motion capabilities ability (27 cm, 34 times body length). Moreover, reversible recombination sliding properties network ensure high toughness (81.9 kJ/mol) efficiency (88.2%), greatly benefit long-term service under complex demanding scenarios. This study provides strategy improve their adaptability stability environments.
