• Soft ionic conductors show great promise in multifunctional iontronic devices, but currently utilized gel materials suffer from liquid leakage or evaporation issues. Here, a dry ion‐conducting elastomer with dynamic crosslinking structures is reported. The dynamic crosslinking structures endow it with combined advantageous properties simultaneously, including high ionic conductivity (2.04 × 10−4 S cm−1 at 25 °C), self‐healing capability (96% healing efficiency), stretchability (563%), and transparency (78%). With this ionic conductor as the electrode, two soft iontronic devices (electroluminescent devices and triboelectric nanogenerator tactile sensors) are realized with entirely self‐healing and stretchable capabilities. Due to the absence of liquid materials, the dry ion‐conducting elastomer shows wide operational temperature range, and the iontronic devices achieve excellent stability. These findings provide a promising strategy to achieve highly conductive and multifunctional soft dry ionic conductors, and demonstrate their great potential in soft iontronics or electronics. Dynamically crosslinked dry ion‐conducting elastomers with exceptional properties of high ionic conductivity, self‐healing capability, stretchability, and transparency are reported. Two self‐healing stretchable iontronic devices (electroluminescent devices and triboelectric nanogenerator tactile sensors) are then realized with excellent environmental stability.
