In　the　time　of　Internet　of　Things(IoT),alternating　current　electroluminescence(ACEL)has　unique　advantages　in　the　fields　of　smart　display　and　human-computer　interaction.However,their　reliance　on　external　high-voltage　AC　power　supplies　poses　challenges　in　terms　of　wearability　and　limits　their　practical　application.This　paper　proposed　an　innovative　scheme　for　preparing　a　feather　triboelectric　nanogenerator(F-TENG)using　recyclable　and　environmentally　friendly　material.The　highest　open-circuit　voltage,short-circuit　current,and　transferred　charge　of　SF6-treated　F-TENGs　can　reach　449　V,63　μA,and　152　nC,which　enables　easy　lighting　of　BaTiO3-doped　ACEL　devices.Using　a　human　electrical　potential,a　single-electrode　F-TENG　is　combined　with　ACEL　device　for　self-powered　fingerprint　recognition　display.These　works　achieve　self-powered　flexible　wearable　ACEL　devices,which　are　not　only　efficient　and　portable　but　also　have　good　application　prospects　in　the　human-computer　interaction,functional　displays,and　wearable　electronic　devices.
