压电摩擦复合式纳米发电机仿真与实验
Simulation and Experiment of Piezoelectric and Triboelectric Hybrid Nanogenerators
摘要
Abstract
In response to the challenges of insufficient output capability and stability in traditional nanogenerators under low-frequency wave conditions,a piezoelectric-triboelectric composite nanogenerator was proposed.It converts wave energy into electricity by driving a polytetrafluoroethylene ball via wave motion,causing the ball to impact a piezoelectric cantilever beam while simultaneously rubbing against a nylon film,thereby achieving hybrid energy harvesting.Using the finite element simulation method,the effects of different tilt angles and excitation frequencies on the stress distribution and output characteristics of the piezoelectric module were systematically analyzed,and the simulation results were validated through experiments.The results show that the output voltages of both the piezoelectric module and the triboelectric module increase monotonically with the tilt angle and excitation frequency.Under the operating condition of a 45° tilt angle and a 2 Hz frequency,the peak output voltage of the piezoelectric module reaches 10.9 V,while that of the triboelectric module reaches 408 mV.The findings verify that the proposed nanogenerator can effectively capture wave energy and convert it into electrical output.关键词
