Triboelectric nanogenerators have received significant research attention in recent years. Structural design plays a critical role in improving the energy harvesting performance of triboelectric nanogenerators. Here, we develop the magnetic capsulate triboelectric nanogenerators (MC-TENG) for energy harvesting under undesirable mechanical excitations. The capsulate TENG are designed to be driven by an oscillation-triggered magnetic force in a holding frame to generate electrical power due to the principle of the freestanding triboelectrification. Experimental and numerical studies are conducted to investigate the electrical performance of MC-TENG under cyclic loading in three energy harvesting modes. The results indicate that the energy harvesting performance of the MC-TENG is significantly affected by the structure of the capsulate TENG. The copper MC-TENG systems are found to be the most effective design that generates the maximum mode of the voltage range is 4 V in the closed-circuit with the resistance of 10 GΩ. The proposed MC-TENG concept provides an effective method to harvest electrical energy from low-frequency and low-amplitude oscillations such as ocean wave.
近年来，摩擦纳米发电机受到了广泛的研究关注。结构设计在提高摩擦纳米发电机的能量收集性能方面起着关键作用。在此，我们开发了磁封装摩擦纳米发电机（MC-TENG），用于在不良机械激励下收集能量。封装式TENG的设计是通过在保持框架中由振荡触发的磁力驱动，根据独立摩擦起电原理产生电能。进行了实验和数值研究，以研究MC-TENG在三种能量收集模式下循环加载时的电性能。结果表明，MC-TENG的能量收集性能受到封装式TENG结构的显著影响。发现铜MC-TENG系统是最有效的设计，在电阻为10 GΩ的闭路中，产生的最大电压范围模式为4 V。所提出的MC-TENG概念提供了一种从诸如海浪等低频和低振幅振荡中收集电能的有效方法。
