The marine internet of things (MIoT), an increasingly important foundation for ocean development and protection, consists of a variety of marine distributed sensors under water. These sensors of the MIoT have always been highly dependent on batteries. To realize in situ power supply, a flexible seaweed-like triboelectric nanogenerator (S-TENG) capable of harvesting wave energy is proposed in this study. The flexible structure, designed with inspiration from the seaweed structure, processes extensive marine application scenarios. The bending and recovering of the S-TENG structure under wave excitations are converted to electricity. As the output performance increases with the number of parallel connected S-TENG units, an S-TENG system with multiple units could serve for floating buoys, coastal power stations, and even submerged devices. Through the demonstration experiments performed in this study, the flexible, low-cost S-TENG could become an effective approach to achieve a battery independent MIoT.

灵活的海藻状摩擦纳米发电机作为波能收集器为海洋物联网提供动力

海洋物联网（MIoT）是海洋开发和保护日益重要的基础，由各种海洋分布式传感器组成。MIoT 的这些传感器一直高度依赖电池。就地实现本研究提出了一种能够收集波浪能的柔性海藻状摩擦纳米发电机（S-TENG）。灵活的结构，灵感来自海藻结构，处理广泛的海洋应用场景。S-TENG 结构在波浪激励下的弯曲和恢复被转换为电能。随着输出性能随着并联 S-TENG 单元数量的增加而增加，具有多个单元的 S-TENG 系统可用于浮标、沿海发电站，甚至水下设备。通过本研究中进行的演示实验，灵活、低成本的 S-TENG 可以成为实现独立于电池的 MIoT 的有效方法。
