Abstract Flexible strain sensors have received tremendous attention because of their potential applications as wearable sensing devices. However, the integration key functions into a single sensor, such high stretchability, low hysteresis, self-adhesion, and excellent antifreezing performance, remains an unmet challenge. In this respect, zwitterionic hydrogels emerged ideal material candidates for breaking through above dilemma. The mechanical properties most reported hydrogels, however, are relatively poor, significantly restricting use under load-bearing conditions. Traditional improvement approaches often involve complex preparation processes, making large-scale production challenging. Additionally, prepared with chemical crosslinkers typically fragile prone to irreversible deformation large strains, resulting in slow recovery structure function. To fundamentally enhance pure effective approach is regulation monomers targeted design strategy. This study employed novel monomer carboxybetaine urethane acrylate (CBUTA), which contained one group on its side chain. Through direct polymerization ultrahigh concentration solutions without adding any crosslinker, we successfully developed supramolecular enhanced properties, self-adhesive behavior, performance. Most importantly, resultant exhibited tensile strength toughness displayed ultralow hysteresis conditions up 1100%. outstanding performance was attributed unique liquid–liquid phase separation phenomenon induced by CBUTA aqueous solution, well polymer chain entanglement strong hydrogen bonds between groups chains. application high-performance triboelectric nanogenerators further explored. Overall, work provides promising strategy developing flexible self-powered electronic
