Implantable Cardiac Pacemaker EMI Triggered by HF-band Wireless Power Transfer Coils

Abstract

We introduce a numerical assessment methodology to understand the EMI imposed by coupledresonant type wireless power transfer systems on active implantable medical devices ( implantable cardiac pacemaker / cardioverter defibrillator). A numerical estimation model that consists of 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 resonant coupling coils operating in the frequency band of 10 MHz.
