Research on triboelectric-piezoelectric energy harvesting technology driven by wind

Abstract In this paper, the triboelectric-piezoelectric energy harvesting technology is systematically studied. Piezoelectric materials and friction materials are combined to form integrated piezoelectric plates. A wind energy harvester based on integrated piezoelectric plates is designed and its performance is evaluated. Experimental results reveal that the maximum peak voltage for piezoelectricity and triboelectricity are 38.91 V and 12.4 V, respectively. Notably, the output voltage of the integrated piezoelectric plate is observed to increase by 31.87% compared to the original piezoelectric plate. The maximum piezoelectric peak voltage of the overall wind energy harvester is 145.23 V, and the maximum triboelectric peak voltage is 43.25 V, which can provide continuous power for small components. The integrated piezoelectric plates demonstrates a substantial enhancement in the original piezoelectric output voltage, indicating significant application potential.
