The development of compact magnetic stimulators will enable us to treat some intractable neurological diseases at one's home. In this study, we propose eccentric spiral coils which induce sufficient eddy currents in the brain at lower driving currents for the stimulator circuit. Numerical simulations based on the finite element method showed the advantages of the proposed design. A prototype coil and driving circuit were fabricated. The coil generated a magnetic field of 1.41 T at the maximum output level of stimulator.
紧凑型磁刺激器的研发将使我们能够在家中治疗一些难治性神经疾病。在本研究中，我们提出了偏心螺旋线圈，其在较低的驱动电流下就能在大脑中感应出足够的涡电流，以用于刺激器电路。基于有限元方法的数值模拟显示了所提设计的优势。制作了一个原型线圈和驱动电路。该线圈在刺激器的最大输出水平下产生了1.41特斯拉的磁场。
