The rapid advancement in attractive platforms such as biomedicine and

human-machine interaction has generated urgent demands for intelligent

materials with high strength, ?exibility, and self-healing capabilities. However,

existing self-healing ability materials are challenged by a trade-o? between

high strength, low elastic modulus, and healing ability due to the inherent low

strength of noncovalent bonding. Here, drawing inspiration from human

?broblasts, a monomer trapping synthesis strategy is presented based on the

dissociation and recon?guration in amphiphilic ionic restrictors (7000-times

volume monomer trapping) to develop a eutectogel. Bene?ting from the

nanocon?nement and dynamic interfacial interactions, the molecular chain

backbone of the formed con?ned domains is mechanically reinforced while

preserving soft movement capabilities. The resulting eutectogels demonstrate

superior mechanical properties (1799% and 2753% higher tensile strength

and toughness than pure polymerized deep eutectic solvent), excellent

self-healing e?ciency (>90%), low tangential modulus (0.367 MPa during the

working stage), and the ability to sensitively monitor human activities. This

strategy is poised to o?er a new perspective for developing high strength, low

modulus, and self-healing wearable electronics tailored to human body

motion.
