Water wave energy is a promising clean energy source, which is abundant but hard to scavenge economically. Triboelectric nanogenerator (TENG) networks provide an effective approach toward massive harvesting of water wave energy in oceans. In this work, a coupling design in TENG networks for such purposes is reported. The charge output of the rationally linked units is over 10 times of that without linkage. TENG networks of three different connecting methods are fabricated and show better performance for the ones with flexible connections. The network is based on an optimized ball-shell structured TENG unit with high responsivity to small agitations. The dynamic behavior of single and multiple TENG units is also investigated comprehensively to fully understand their performance in water. The study shows that a rational design on the linkage among the units could be an effective strategy for TENG clusters to operate collaboratively for reaching a higher performance.
水波能是一种很有前途的清洁能源，它虽然丰富，但很难从经济上加以利用。摩擦纳米发电机（TENG）网络为大规模获取海洋中的水波能提供了一种有效的方法。在这项工作中，报道了一种用于此目的的 TENG 网络的耦合设计。合理连接的单元的电荷输出是没有连接的单元的 10 多倍。制造了三种不同连接方式的 TENG 网络，具有灵活连接的网络表现更好。该网络基于具有高响应性的优化的球壳结构 TENG 单元，对小的搅动敏感。还全面研究了单个和多个 TENG 单元的动态行为，以充分了解它们在水中的性能。研究表明，在单元之间的连接上进行合理的设计可以是 TENG 集群协同运行以达到更高性能的有效策略。
