Triboelectric　nanogenerator　(TENG)　has　gained　widespread　applications　due　to　their　unique　ability　to　convert　various　forms　of　mechanical　energy,　such　as　wind　and　tidal　energy,　into　electrical　power.　However,　a　critical　challenge　lies　in　maintaining　high　efficiency　and　stability　amid　fluctuating　environmental　temperatures.　From　a　materials　perspective,　it　has　been　observed　that　the　dielectric　constant　of　the　frictional　triboelectric　layer　material　is　influenced　by　temperature　variations,　significantly　impacting　TENG　performance.　To　address　this,　our　study　employed　Ba(Cu　0.5　W　0.5　)O　3　(BCW)-based　ceramic　powder　to　develop　temperature　-stable　materials　with　a　high　dielectric　constant.　These　materials　were　combined　with　PDMS　to　create　a　composite　thin　film　for　the　TENG　frictional　triboelectric　layer.　This　novel　composite　thin　film　-based　TENG　exhibited　remarkable　electrical　properties,　including　an　open　-circuit　voltage　(V　OC　)　of　127　V　and　a　short-circuit　current　(I　SC　)　of　3.16　mu　A,　surpassing　conventional　PDMS　thin　film　-based　TENGs　that　achieved　values　of　22　V　and　0.65　mu　A,　respectively.　From　-10　degrees　C　to　180　degrees　C,　the　relative　change　for　V　OC　is　24.6　%,　while　for　I　SC　is　28.3　%.　Additionally,　the　BCW-based/PDMS　TENG　demonstrated　the　capability　to　simultaneously　power　54　LEDs,　showcasing　its　potential　as　a　versatile　self　-powered　device.　Our　study　not　only　advanced　TENG　performance　from　a　material　standpoint　but　also　mitigated　its　sensitivity　to　environmental　temperature,　thereby　expanding　its　promising　applications　in　diverse　scenarios.
