Ocean waves are considered to be one of the most promising renewable energy sources, and harvesting such energy via triboelectric nanogenerators (TENGs) is an effective strategy toward large‐scale blue energy. However, most previous optimization schemes of TENG cannot meet the demands of practical applications. In this work, a new charge excitation circuit (CEC) with advantages of integration, high efficiency, and minimum impedance is developed specially for TENGs to harvest water wave energy. The TENG with the CEC exhibits significantly improved output performance, with a maximum power of 25.8 mW and power density of 49.3 W m⁻³, and a 208 times enhanced current of 25.1 mA is achieved. Furthermore, a scheme of integrating TENG network and CECs is proposed for realizing large‐scale wave energy harvesting. The charge excitation TENG network is demonstrated to successfully power a digital thermometer and a wireless communication system with mobile phone through transmitting radio frequency (RF) signals for remote environmental monitoring. This study not only offers a strategy to greatly enhance the output performance of TENG networks in water wave energy harvesting, but also provides useful guidance for constructing maritime communication platform based on blue energy toward a maritime internet of things system.

集成电荷激发电路的摩擦纳米发电机网络，有效收集水波能量

海浪被认为是最有前途的可再生能源之一，通过摩擦电纳米发电机（TENGs）收集此类能源是迈向大规模蓝色能源的有效策略。但是，TENG以前的大多数优化方案都无法满足实际应用的需求。在这项工作中，专门为TENG收集水波能量而开发了一种具有集成度，高效率和最小阻抗优势的新型电荷激励电路（CEC）。具有CEC的TENG表现出显着改善的输出性能，最大功率为25.8 mW，功率密度为49.3 W m ^-3，实现了25.1 mA的208倍增强电流。提出了一种将TENG网络与CEC集成的方案，以实现大规模的波能收集。演示了电荷激励TENG网络，该系统通过传输射频（RF）信号进行远程环境监测，成功为数字温度计和带有手机的无线通信系统供电。该研究不仅为提高TENG网络在水波能量收集中的输出性能提供了一种策略，而且为构建基于蓝色能源的海洋通信平台向海洋物联网系统提供了有益的指导。
