| Summary: | Wearable devices for human health monitoring have gained significant attention in recent years, offering innovative solutions for tracking physiological parameters and supporting personalized healthcare management. This study introduces a polyvinylidene fluoride/polyacrylonitrile (PVDF/PAN) electrospun film-based triboelectric nanogenerator (PP-TENG) for efficient mechanical energy harvesting. The PVDF/PAN film, optimized at 4% PAN concentration, serves as the negative triboelectric material, paired with a Nylon positive counterpart. The PVDF/PAN composite film demonstrates remarkable performance improvements over the pure PVDF film. The enhancements include over 2.3 times higher open-circuit voltage (VOC), 2.72 times higher short-circuit current (ISC), and 1.92 times greater transferred charge (QSC). The PP-TENG achieves an VOC of 160 V, a ISC of 60 μA, and a QSC of 87 nC, with a peak power output of 1.99 mW at a 2 MΩ load resistance. The PP-TENG is a versatile and efficient device for energy harvesting and self-powered health monitoring, excelling in motion tracking, respiratory monitoring, and gait analysis while being sensitive to environmental factors like humidity. This research highlights the potential of the PP-TENG as an efficient energy harvester and versatile platform for wearable health monitoring and self-powered healthcare applications. |
