The energy crisis and environmental pollution are the two major challenges facing humanity, and harvesting energy from the ocean is a promising solution. In this paper, a triboelectric-electromagnetic-piezoelectric hybrid energy harvester (TEP-HEH) for low frequency wave energy harvesting is presented. With the introduction of the cantilever beam structure, the vibration frequency is converted from 0.2 Hz (simulated wave frequency) to 7.2 Hz, which greatly improves the energy harvesting performance of the electromagnetic generator (EMG) and the piezoelectric nanogenerator (PENG) modules. By broadening the frequency bandwidth of wave energy harvesting, a large power density of 5.73 W m⁻³ is obtained for the TEP-HEH. Besides, the output performance of TENG, EMG, and PENG modules is investigated and the connection mode of the three types of modules is discussed. The TEP-HEH can light up a commercial lighting bulb with a rated power of 5 W or power small electronics. This work provides an efficient solution for low frequency wave energy harvesting and the realization of the blue-energy dream.

能源危机和环境污染是人类面临的两大挑战，从海洋中获取能源是一个很有前景的解决方案。本文介绍了一种用于低频波能量收集的摩擦电-电磁-压电混合能量收集器 (TEP-HEH)。随着悬臂梁结构的引入，振动频率从0.2 Hz（模拟波频率）转换为7.2 Hz，大大提高了电磁发电机（EMG）和压电纳米发电机（PENG）模块的能量收集性能。^{通过拓宽波浪能收集的频率带宽，5.73 W m -3}的大功率密度为 TEP-HEH 获得。此外，研究了TENG、EMG和PENG模块的输出性能，并讨论了三种模块的连接方式。TEP-HEH 可以点亮额定功率为 5 W 的商用灯泡或为小型电子设备供电。这项工作为低频波能量收集和蓝色能量梦想的实现提供了一种有效的解决方案。
