The movement of the creature and the almost wave in the ocean is a low vibration of random energy with a frequency range of 0.1–10 Hz. Because of its low frequency, the opinion has been that electrical energy generation from this low-frequency wave motion through the electromagnetic induction method is difficult. In this study, an electrical generator was created by the electromagnetic induction method by putting a small mass of ferromagnetic powder in nonmagnetic fluid. A broadband vibration energy harvesting model was created in which vibrations are broadened through a multi-degree of freedom oscillation system using ferromagnetic powder. To generate electricity from low-frequency vibrations (1 Hz or less), a non-resonant type model was created by adding fluid to the ferromagnetic powder model and the simulation results confirmed using computational fluid dynamics by creating a working energy harvesting device.

铁磁粉末与非磁性流体低频振动能量收集的研究

生物的运动和几乎在海洋中的波浪是随机能量的低振动，频率范围为0.1–10 Hz。由于其低频，人们认为很难通过电磁感应方法从这种低频波运动中产生电能。在这项研究中，通过将少量铁磁粉末放入非磁性流体中，通过电磁感应方法产生了发电机。创建了宽带振动能量收集模型，其中通过使用铁磁粉末的多自由度振荡系统来扩展振动。为了从低频振动（小于或等于1 Hz）产生电流，
