在本文中，我们提出了一种利用磁性弹性体的变形来收集振动能量的发电方法。设计合理的磁性弹性体结构在静磁场作用下进行膨胀和收缩，可以显著改变磁性弹性体结构的磁通线。我们在磁性弹性体上设置了一个线圈，通过捕捉磁通量的变化来发电。我们制作了一个厘米级的装置，并证明了它在10赫兹的振动下产生10.5 mV的最大电压。利用有限元方法模拟了磁通流的变化，并与实验数据进行了比较。此外，我们评估了一个小型化装置的发电。
In this paper, we propose a power generation method using the deformation of a magnetic elastomer for vibration energy harvesting. The magnetic flux lines in the structure of the magnetic elastomer could be markedly changed if the properly designed structure was expanded and contracted in a static magnetic field. We set a coil on the magnetic elastomer to generate electricity by capturing this change in magnetic flux flow. We fabricated a centimeter-scale device and demonstrated that it generated 10.5 mV of maximum voltage by 10 Hz vibration. We also simulated the change in the magnetic flux flow using finite element analysis, and compared the result with the experimental data. Furthermore, we evaluated the power generation of a miniaturized device.
