Triboelectric nanogenerators (TENGs) show great potential for wave energy harvesting. However, the low frequency and chaotic nature make it difficult for TENGs to generate stable electrical outputs, posing challenges for directly powering electronics and designing universal power management circuits. Inspired by the consistent and steady energy output of octave boxes, we propose a novel energy regularization triboelectric nanogenerator (ER-TENG). Chaotic wave energy is temporarily stored in coil springs by one-way bearings and then converted into a controlled rotation to drive TENGs through the synergistic effect of a gear set and a centrifugal speed limiter. The relationship between the rotational speed and the configuration of the gear set/centrifugal speed limiter is investigated to optimize the mechanical transmission efficiency. Moreover, the utilization of ternary dielectric materials and multi-layer stacked units enhances the electro-mechanical conversion efficiency, resulting in an average power density of up to 15.67 W m⁻³. Fast charging of capacitors is achieved through the ER-TENG using a simple power management circuit. In practical applications, the ER-TENG demonstrates the capability to continuously power offshore appliances. This energy regularization strategy enables TENGs to directly output a stable signal, which serves as a significant reference for the development of smart ocean systems.

一个受倍频程盒启发的能量正则化摩擦纳米发电机，用于高效波能收集


摩擦纳米发电机 （TENG） 显示出波浪能收集的巨大潜力。然而，低频和混沌特性使 TENG 难以产生稳定的电输出，这对直接为电子设备供电和设计通用电源管理电路提出了挑战。受到倍频程箱一致和稳定的能量输出的启发，我们提出了一种新型能量正则化摩擦纳米发电机 （ER-TENG）。混沌波能通过单向轴承暂时储存在螺旋弹簧中，然后转化为受控旋转，通过齿轮组和离心限速器的协同作用驱动 TENG。研究了转速与齿轮组/离心限速器配置之间的关系，以优化机械传动效率。此外，三元介电材料和多层堆叠单元的使用提高了机电转换效率，从而产生高达 15.67 W ^m-3 的平均功率密度。电容器的快速充电是通过 ER-TENG 使用简单的电源管理电路实现的。在实际应用中，ER-TENG 展示了为海上设备持续供电的能力。这种能量正则化策略使 TENG 能够直接输出稳定的信号，为智能海洋系统的发展提供了重要的参考。
