The　development　of　artificial　skin,　such　as　electronic　skin,　is　critical　to　emerging　artificial　intelligence　systems.　Electronic　skins　reported　to　date　are　mechanically　flexible,　and　can　detect　various　stimuli,　but　lack　the　ability　to　regulate　themselves　and　learn　information　from　the　outside　world.　The　integration　of　bio-inspired　multifunction　in　a　single　electronic　platform　is　critical　to　the　development　of　e-skin　systems.　Here,　we　demonstrate　a　self-powered,　light-stimulated,　smart　e-skin　based　on　a　photosensitive　perovskite　material.　The　electronic　skin　implements　the　functions　of　both　tactile　sensing　and　photoelectric　neural　computing.　The　strategy　for　developing　such　a　material　system　and　architecture　of　the　electronic　skin　meets　the　requirement　of　multifunctional　smart　human-machine　interfaces　and　has　promising　potential　for　application　in　future　artificial　intelligence　systems.
