Abstract Triboelectric nanogenerators (TENGs) have become reliable green energy harvesters by converting biomechanical motions into electricity. However, the inevitable charge leakage and poor electric field (EF) of conventional TENG result in inferior tribo‐charge density on active layer. In this paper, TiO 2 ‐MXene incorporated polystyrene (PS) nanofiber membrane (PTMx NFM) trapping interlayer is introduced single electrode mode (S‐TENG) to prevent electron loss at interface. Surprisingly, charge‐trapping mechanism augments surface output performance TENGs. Polyvinylidene difluoride (PVDF) mixed polyurethane (PU) NFM used as tribo‐active layer, which improves crystallinity mechanical property PVDF delamination during long cycle tests. Herein, effect double‐layer capacitive model explained experimentally theoretically. With optimization PTMx thickness, S‐TENG exhibits a maximum open‐circuit voltage (280 V), short‐circuit current (20 µA) transfer (120 nC), power (25.2 µW cm −2 ). Then, utilized electrical appliances. addition, influence AC/DC EF simulation wound healing management (vitro L929 cell migration, vivo tissue regeneration) also investigated changing polarity trans‐epithelial potential (TEP) distribution wounded area.
