Abstract

This paper provides a numerical simulation study of Magnetically Circular Layers of Triboelectric Nanogenerators (MCL-TENGs) for energy harvesting and self-powered sensing. The MCL-TENGs generate electrical energy by means of the conversion of mechanical energy into electrical energy through contact electrification and electrostatic induction. This paper concentrates on the numerical modeling of the copper/aluminum MCL-TENG and compares simulation results with experimental findings. The voltage comparison of copper MCL-TENGs (OC) between experimental and numerical simulations at 2000, 2500, and 3000 rpm showed Cu-EXP configuration voltages ranging from 4.1 to 4.4 V and Cu-FEM setup voltages ranging from 4 to 4.4 V. Meanwhile, aluminum MCL-TENGs showed Al-EXP configuration voltages ranging from 4.08 to 4.35 V and Al-FEM setup voltages ranging from 4 to 4.3 V across the third layer. The system can enhance the energy efficiency and sustainability of coastal bridge infrastructure by harvesting surplus energy from mechanical motion and converting it to electricity for self-powered sensing and monitoring systems.

先进自感应复合材料的磁环形层状三电纳米发电机

本文对用于能量收集和自供电传感的磁性环形层三电纳米发电机（MCL-TENGs）进行了数值模拟研究。MCL-TENG 通过接触电化和静电感应将机械能转化为电能的方式产生电能。本文主要研究铜/铝 MCL-TENG 的数值建模，并将模拟结果与实验结果进行比较。铜 MCL-TENG （OC）在 2000、2500 和 3000 rpm 转速下的实验和数值模拟电压比较显示，Cu-EXP 配置电压范围为 4.1 至 4.4 V，Cu-FEM 设置电压范围为 4 至 4.4 V。同时，铝 MCL-TENG 在第三层显示出 4.08 至 4.35 V 的 Al-EXP 配置电压和 4 至 4.3 V 的 Al-FEM 设置电压。该系统可从机械运动中收集剩余能量并将其转化为电力，用于自供电传感和监测系统，从而提高沿海桥梁基础设施的能源效率和可持续性。
