Triboelectric nanogeneration is a burgeoning and promising technology for harvesting low-frequency mechanical energy from the environment, but the energy conversion efficiency and service life of the triboelectric nanogenerator (TENG) device are limited by the inevitable frictional resistance between the tribo-surfaces. Herein, we propose an electrostatic induction nanogenerator (EING) circulation network (EICN) by integrating an arbitrary number of EING units for harvesting low-frequency mechanical energy. Because of absolute conquering of the friction resistance between the tribo-surfaces, the average power density of the EING device in the EICN by the initial charge injection (from a TENG or a power supply) is more than a 15-fold enhancement compared with the previous swing-structured TENG. The EICN can recover to the stable and optimal electrical output state in 90 s without external charge injection, even if the external triggering interrupts for 40 min and then restarts, demonstrating the excellent application feasibility of this strategy. To display the practical application scenario for harvesting large-scale mechanical energy from the environment, a high-performance and ultralow-friction TENG is designed for the initial charge injection to the EICN. Moreover, portable electronic devices are powered successfully to realize the self-powered sensing and remote marine environmental monitoring when an EICN with three EINGs is triggered by the real water wave. This EICN strategy not only can harvest low-frequency swing type mechanical energy but also has the capacity of harvesting the rotational mechanical energy after reasonable structure modification, providing an excellent candidate for large-scale blue energy harvesting in practical applications.

最初由摩擦电纳米发电机充电的超耐用且高效的静电感应纳米发电机循环网络，用于收集环境能量

摩擦电纳米发电是一种新兴的，有前途的技术，可以从环境中获取低频机械能，但是摩擦电纳米发电机（TENG）装置的能量转换效率和使用寿命受到摩擦表面之间不可避免的摩擦阻力的限制。本文中，我们通过集成任意数量的EING单元来收集低频机械能，提出了一种静电感应纳米发电机（EING）循环网络（EICN）。由于摩擦表面之间的摩擦阻力得到了绝对的克服，因此，通过初始电荷注入（来自TENG或电源），EICN中的EING装置的平均功率密度提高了15倍以上。以前的秋千结构的TENG。即使外部触发中断40分钟然后重新启动，EICN仍可以在90 s内恢复到稳定和最佳的电输出状态，即使外部触发中断40分钟然后重新启动，也证明了该策略的出色应用可行性。为了展示从环境中收集大规模机械能的实际应用场景，针对向EICN的初始电荷注入设计了一种高性能且超低摩擦的TENG。此外，当真实水波触发具有三个EING的EICN时，便携式电子设备将成功供电，以实现自供电的传感和远程海洋环境监控。
