Abstract Triboelectric energy harvester (TEH) is an emerging technology that has been recently demonstrated to harvest mechanical energy. The TEH can be fabricated in various configurations due to their flexibility in nature and therefore have a wide number of applications. In this paper, a simplified model of vertical contact mode triboelectric energy harvester has been presented. Commercial Polydimethylsiloxane (PDMS) and thin copper film have been considered for the generation of tribocharge. The effects of various design parameters and the load resistance on the harvested power are investigated under a periodic harmonic motion. Numerical results predicted that harvested power depends upon surface area, relative permittivity, surface charge density and dielectric thickness of triboelectric material, the frequency of contact, distance between the electrodes and load resistance. Finally, the optimization of design parameters using genetic algorithms is studied in order to provide sufficient guidance for the rational development of TEH. Simulated results predicted that triboelectric harvesters can generate a significant amount of energy that can operate small electronics like cell phones, robots, navigation systems, motion, and biological sensors.

垂直接触式摩擦电能收集器的建模与分析

摘要 摩擦电能收集器 (TEH) 是一项新兴技术,最近已被证明用于收集机械能。由于其本质上的灵活性,TEH 可以以各种配置制造,因此具有广泛的应用。在本文中,提出了一种垂直接触模式摩擦电能收集器的简化模型。商业聚二甲基硅氧烷 (PDMS) 和薄铜膜已被考虑用于产生摩擦电荷。在周期性谐波运动下研究了各种设计参数和负载电阻对收获功率的影响。数值结果预测,收获的功率取决于摩擦电材料的表面积、相对介电常数、表面电荷密度和介电厚度、接触频率、电极之间的距离和负载电阻。最后,研究了利用遗传算法优化设计参数,为TEH的合理发展提供充分的指导。模拟结果预测,摩擦电采集器可以产生大量能量,可以操作手机、机器人、导航系统、运动和生物传感器等小型电子设备。
