Abstract Stretchable ionic skins are intriguing in mimicking the versatile sensations of natural skins. However, for their applications advanced electronics, good elastic recovery, self-healing, and more importantly, skin-like nonlinear mechanoresponse (strain-stiffening) essential but can be rarely met one material. Here we demonstrate a robust proton-conductive skin design via introducing an entropy-driven supramolecular zwitterionic reorganizable network to hydrogen-bonded polycarboxylic acid network. The allows two dynamic networks with distinct interacting strength sequentially debond stretch, conflict among elasticity, strain-stiffening thus defeated. representative polyacrylic acid/betaine elastomer exhibits high stretchability (1600% elongation), immense (24-fold modulus enhancement), ~100% excellent elasticity (97.9 ± 1.1% recovery ratio, <14% hysteresis), transparency (99.7 0.1%), moisture-preserving, anti-freezing (elastic at −40 °C), water reprocessibility, as well easy-to-peel adhesion. combined advantages make present very promising wearable iontronic sensors human-machine interfacing.
