The CAP conductor is stretchable and self-healable due to ionic hydrogen bonding between the CA DESs and desulfurized PEDOT moieties. After treatment with sulfuric acid, structural rearrangement boosted the electrical conductivity of CAP by more than 100 times, achieving fast signal responses at high stretch─release rates and long-term anti-fatigue. Desulfurized CAP can realize a multifunctional smart wearable sensor. English Pergamon Press Ltd.
