Abstract

The performance of the stimulation coil in a magnetic nerve stimulator can be improved by attaching a ferromagnetic structure to the coil. This reduces heat generation at the coil and increases magnetic field strength for a given unit of current. Some technical aspects of the design of a stimulation coil with a ferromagnetic structure have been studied. Finite element method analysis results are presented for the effect of size, depth and magnetic saturation of the ferromagnetic structure on the stimulation coil performance. The experimental results show that the stimulation coil performance is improved by up to 40% by the attaching of a ferromagnetic structure on the coil.

摘要

通过在磁神经刺激器的刺激线圈上附加一个铁磁结构，可以提高其性能。这减少了线圈处的热量产生，并在给定电流单位下增加了磁场强度。已经研究了带有铁磁结构的刺激线圈设计的一些技术方面。给出了有限元方法分析结果，以说明铁磁结构的尺寸、深度和磁饱和度对刺激线圈性能的影响。实验结果表明，通过在线圈上附加铁磁结构，刺激线圈的性能可提高多达40%。
