海洋物联网（MIoT）由多种水下海洋分布式传感器组成，是海洋开发和保护日益重要的基础。这些物联网的传感器一直高度依赖于电池。为了实现原位供电，本研究提出了一种能够收集波浪能的柔性海藻状摩擦电纳米发电机（S-TENG）。灵活的结构，设计灵感来自海藻结构，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转化为电能。由于输出性能随着并联S-TENG单元数量的增加而增加，具有多个单元的S-TENG系统可以用于浮动浮标，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可以成为实现不依赖电池的MIoT的有效方法。
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.
