Abstract Artificial skin should embody a softly functional film that is capable of self-powering, healing and sensing with neuromorphic processing. However, the pursuit of a bionic skin that combines high flexibility, self-healability, and zero-powered photosynaptic functionality remains elusive. In this study, we report a self-powered and self-healable neuromorphic vision skin, featuring silver nanoparticle-doped ionogel heterostructure as photoacceptor. The localized surface plasmon resonance induced by light in the nanoparticles triggers temperature fluctuations within the heterojunction, facilitating ion migration for visual sensing with synaptic behaviors. The abundant reversible hydrogen bonds in the ionogel endow the skin with remarkable mechanical flexibility and self-healing properties. We assembled a neuromorphic visual skin equipped with a 5 × 5 photosynapse array, capable of sensing and memorizing diverse light patterns.
