The　development　of　electronic-skin　(e-skin)　with　artificial　tactile-perception　is　crucial　for　emerging　artificial-intelligence　systems.　However,　considering　the　relatively　simple　function　of　existing　e-skins,　their　performances　still　have　much　room　for　improvement.　Here,　a　cuttable,　transparent,　stretchable,　and　lightweight　e-skin　that　functions　on　the　basis　of　the　triboelectric　effect　is　demonstrated.　Well-designed　micro-gaps　are　introduced　to　make　the　e-skin　respond　sensitively　to　various　mechanical　stimulations,　including　pressing,　stretching,　folding,　and　twisting.　Ag　nanowires　coated　with　graphene　quantum　dots　are　employed　as　the　electrode,　as　well　as　the　friction　layer,　to　increase　the　sensitivity　to　external　mechanical　stimulations.　Self-powered,　smart,　artificial　fingers　with　tactile　sensation　to　monitor　the　actions　of　the　fingers　were　fabricated　to　demonstrate　the　potential　application　of　our　newly　developed　e-skin.　The　architecture　and　the　material　system　of　the　device　demonstrated　in　this　work　will　promote　the　development　of　human-machine　interfaces　and　intelligent　machines.　©　2018
