Artificial skin should embody a softly functional film that is capable of self-powering,healing and sensing with neuro-morphic processing.However,the pursuit of a bionic skin that combines high flexibility,self-healability,and zero-powered pho-tosynaptic functionality remains elusive.In this study,we report a self-powered and self-healable neuromorphic vision skin,fea-turing 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 sens-ing with synaptic behaviors.The abundant reversible hydrogen bonds in the ionogel endow the skin with remarkable mechani-cal 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.
