Multidirectional irregular breaking wave is the most prominent feature of the ocean surface and bears tremendous amounts of sustainable high-entropy energy. However, the commercial utilization and harvesting efficiency are very limited low due to its low-frequency and low-amplitude. Here, a swing self-regulated triboelectric nanogenerator (SSR-TENG) is proposed, which can convert collected low-grade breaking waves energy into electrical energy by regulating the oscillation frequency and resonance effect. Benefiting from simple and efficient structural strategy, SSR-TENG outputs a peak power of 0.14 mW under wave height range of 6–11 cm, that the open-circuit voltage, short-circuit current and transferred charge increases is 5.8, 4, and 3.7 times compared to without self-regulated design, respectively. This work gives a practical solution to the problems faced by harvesting high-entropy ocean breaking waves energy, which exhibits large potential for building the self-powered ocean assessment and meteorology system in the future.

用于高熵海洋碎浪能量收集的摆动自调节摩擦纳米发电机

多向不规则破碎波是海洋表面最显着的特征，蕴藏着巨大的可持续高熵能量。但由于其频率低、幅度低，其商业利用和收获效率非常有限。在此，提出了一种摆动自调节摩擦纳米发电机（SSR-TENG），它可以通过调节振荡频率和共振效应将收集的低品位碎波能量转化为电能。得益于简单高效的结构策略，SSR-TENG在6-11 cm波高范围内输出0.14 mW的峰值功率，开路电压、短路电流和转移电荷分别增加5.8、4和3.7分别与没有自调节设计的时间相比。这项工作为收集高熵海洋碎浪能量所面临的问题提供了切实可行的解决方案，为未来构建自供电海洋评估和气象系统展现了巨大的潜力。
