Utilizing this oscillator, the Flow-induced motion energy conversion system (FIMECS) can effectively utilize ocean current energy. Simultaneously, oscillators of various shapes are compared, and experimental data are analyzed in this article. Additionally, Visual analysis is added to the result analysis in this article, expanding the range of low water current velocity measurements from 0.05 m/s to 0.75 m/s. The results demonstrate that compared with the traditional circular oscillator structure, the Circular-attachments Oscillator and Circular-T shaped-appendage Oscillator improve the energy harvesting performance. The integrated device has the potential to serve as a self-powered water current velocity sensor and a subsea micropower supply simultaneously, offering a versatile solution for energy harvesting from low-velocity ocean currents. Thus, this reviewer recommends this article be published in Frontiers In Marine Science. However, several questions need to be addressed before the final acceptance.
