Electrospun materials are ideal substrates for wearable devices, offering high surface area, porosity, and mechanical flexibility. A polyimide/MXene (MXene) spinning film cellulose acetate/polyamide 6 were used to fabricate a triboelectric nanogenerator (PC-TENG) efficient energy harvesting. The results identify 5% MXene as the optimal weight fraction, achieving maximum performance by balancing material properties enhanced conversion. PC-TENG achieves peak power output of 1.16 mW at an load resistance 10 MΩ. While open-circuit voltage (VOC, ∼105 V) transferred charge (QSC, ∼63.14 nC) remain stable across 2–6 Hz, short-circuit current (ISC) increases significantly from 14.91 μA 2 Hz 41.41 Hz. strong linear correlation between applied force is observed, with VOC rising 63.41 V N 148.14 50 N, ISC 7.31 17.98 μA, QSC 29.69 69.73 nC, demonstrating device’s potential precise sensing. Integration into table tennis paddle highlights its applicability in real-time sports monitoring, while frequency-responsive underscores adaptability dynamic sensing scenarios. This research demonstrates PC-TENG’s harvesting sensing, innovative solutions self-powered devices monitoring systems.
