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