摘要

介绍了一种数值评估方法，以了解磁共振型无线电力传输系统对有源植入式医疗设备(植入式心脏起搏器/心律转复除颤器)施加的电磁干扰。建立了一个由磁谐振线圈和人体躯干模型及起搏器模型组成的数值估计模型。基于有限元法的数值模拟得到了躯干体内起搏器连接器处产生的干扰电压。我们的例子假设磁共振线圈工作在10兆赫兹的频段。

Numerical assessment method for implantable cardiac pacemaker EMI triggered by 10MHz-band wireless power transfer coils

A numerical assessment methodology to understand the EMI imposed by magnetic resonance type wireless power transfer systems on active implantable medical devices (implantable cardiac pacemaker/cardioverter defibrillator) is introduced. A numerical estimation model that consists of magnetic resonant coils and a human torso phantom with a pacemaker model is constructed. Numerical simulation based on the finite element method yields the interference voltage induced at the connector of the pacemaker inside the torso phantom. Our example assumes magnetic resonance coils operating in the frequency band of 10 MHz.
