Portable　light　emitting　devices　without　the　need　of　an　external　power　sources　have　attracted　a　wide　range　of　research　hotspots　due　to　their　great　potential　for　wearable　displays,　smart　electronics　and　electronic　skins.　In　this　work,　a　novel　single-electrode　mode　alternating　current　electroluminescence　devices　with　epidermal　potential　as　another　stimulation　electrode　(namely　EPSE-ACEL)　allowing　for　the　simultaneous　sensing　and　display　of　biological　information　has　been　presented.　The　EPSE-ACEL　device　only　consists　of　a　composited　emissive　layer　and　a　transparent　electrode,　which　can　be　easily　attached　to　any　position　on　the　human　body　and　self-powered　by　the　natural　triboelectrification　and　the　static　charges　on　the　human　body.　It　is　demonstrated　that　the　EPSE-ACEL　device　can　be　used　in　fingerprint　display　and　wireless　wearable　display.　The　EPSE-ACEL　device　is　promising　in　various　applications　such　as　human-computer　interaction,　health-care　monitoring,　and　intelligent　wearable　equipment.
