摘要:

基于电力系统中磁能丰富且分布广泛的特点,提出了一种摩擦式磁能收集器结构。通过搭建磁能收集测试平台,从磁场强度、材料厚度以及环境湿度变化等方面对磁能收集器电学输出性能进行测试分析。实验结果表明:随着磁场强度增大,磁能收集器的输出电压与输出电流随之增大,最大瞬时输出功率从846 μW提升到4 400 μW,输出功率提高了4.2倍;随着PDMS材料厚度的降低,磁能收集器输出开路电压与短路电流均呈现先增大后降低的趋势;随着相对湿度增加,基于摩擦式磁能收集器输出开路电压与短路电流均呈现降低的趋势。

Abstract:

A triboelectric magnetic energy harvester structure is proposed based on the abundant and widely distributed magnetic energy in power systems.By building a magnetic energy harvesting test platform,the electrical output performance of the magnetic energy harvester is tested and analyzed in terms of magnetic field strength,material thickness,and environmental humidity variation.The experimental results show that the output voltage and current of the magnetic energy harvester increase with the increase of magnetic field strength,and the maximum instantaneous output power increases from 846 μW to 4 400 μW,which increases the output power by 4.2 times.With the decrease of PDMS material thickness,the output open circuit voltage and short circuit current of the magnetic energy harvester increase first and then decrease.With the increase of relative humidity,the output open-circuit voltage and short-circuit current of the triboelectric magnetic energy harvester both show a decreasing trend.

Key words: magnetic energy harvester, triboelectric nanogenerator, magneto-mechano-electric effect, self-supplied energy
