Electrospinning techniques have been widely applied in diverse applications, such as biocompatible membranes, energy storage systems, and triboelectric nanogenerators (TENGs), with the capability to incorporate other functional materials achieve specific purposes. Recently, gas sensors incorporating doped semiconducting fabricated by electrospinning extensively investigated. TENGs, functioning self-powered sources, utilized drive without external power supplies. Herein, a ethanol sensor (TEES) is integrating TENG an into single device. The proposed TEES exhibits significantly improved response time lower detection limit compared published integrated sensors. device achieves open-circuit voltage of 51.24 V at 800 rpm maximum short-circuit current 7.94 μA rpm. Owing non-contact freestanding operating mode, shows no significant degradation after 240,000 operational cycles. Compared previous studies that TENGs sensors, demonstrated marked improvement sensing performance, faster (6 s 1000 ppm) (10 ppm). Furthermore, enabled modulating gate terminal IRF840 metal-oxide semiconductor field-effect transistor (MOSFET), which controls illumination light-emitting diode (LED). LED extinguished when electrical output decreases below setting value, allowing for discrimination intoxicated states. These results suggest provides promising platform self-powered, high-performance sensing.
