Catechol-based hydrogels have good adhesion properties; however, since the concentration of catechol is low and it can be easily oxidized to quinone, performance reduced, which limits their application as self-adhesive flexible wearable sensors. In this work, a dopamine: poly(sodium 4-styrenesulfonate) (DA:PSS)-initiated strategy was proposed construct adhesive hydrogels, where semiquinone radicals present in DA:PSS were used initiate radical polymerization obtain DA:PSS/poly(acrylic acid) (DA:PSS/PAA) hydrogel. This hydrogel exhibited stretchability with various substrates. We observed that, even after exposure air for 21 days under certain relative humidity (76%), groups hardly DA:PSS/PAA presented adhesion. The also showed electrical conductivity fast response ability. Thus, general triggering monomer form based on offers great potential electronic devices
