In situ harvesting undersea energy is a vital method for undersea detector to realize its long‐term and real‐time undersea research. Herein, inspired by the fins with excellent hydrodynamic characteristic and the triboelectric nanogenerator (TENG) with the merits of light‐weight and high‐efficiency at low frequency, an energy harvesting device is designed to harvest undersea energy by bionic‐fin‐structure assisted with multilayer‐structured triboelectric nanogenerator (BFM‐TENG). The good design of geometry and structure enable BFM‐TENG to harvest energy efficiently by the driving of water‐flow from multidirections. Besides, based on the multiarea contact structure and ultrathin dielectric material, the BFM‐TENG could achieve a peak power density of 444 W m⁻³ under ideal test condition, which is about 1–2 orders of magnitude higher than that of previous work for harvesting wave energy. The findings not only provide a new in situ undersea energy harvesting method for undersea detectors to realize the real‐time, long‐term, and self‐powered undersea research, but also provide a potential strategy to achieve large‐scale undersea energy harvesting.

用于海底能量收集的仿生-鳍结构的摩擦电纳米发电机

现场采集海底能量是海底探测器实现其长期和实时海底研究的重要方法。在此，受具有出色水动力特性的鳍片和具有轻量级且在低频下具有高效率优点的摩擦纳米发电机（TENG）的启发，设计了一种能量收集装置，该装置旨在利用仿生鳍片结构辅助收集海底能量多层结构摩擦电纳米发电机（BFM-TENG）。良好的几何结构设计使BFM-TENG能够通过多方向驱动水流有效地收集能量。此外，基于多区域接触结构和超薄介电材料，BFM-TENG可以实现444 W m ^-3的峰值功率密度在理想的测试条件下，比以前的波能收集工作要高约1-2个数量级。这些发现不仅为海底探测器提供了一种新的就地海底能量采集方法，以实现实时，长期，自供电的海底研究，而且还提供了实现大规模海底能量采集的潜在策略。
