This paper deals with the assessment of the induced voltage in an unipolar pacing lead produced by the coil currents of a wireless power transfer (WPT) system for battery recharging of an electric vehicle (EV). In the first part of the work, the magnetic field distributions inside and outside an EV equipped with the WPT technology is carried out by finite element (FE) simulations using the artificial material single layer (AMSL) method.

This paper deals with the intrasystem electromagnetic interference (EMI) in a pacemaker equipped with a wireless power transfer (WPT) charging system. The WPT application to pacemakers is very new, and no results are yet published on possible EMI effects produced by the WPT coil currents in the pacemaker pacing leads. To this aim, an efficient and original co-simulation circuit/field method is proposed to predict the induced voltages on a pacing lead. In the numerical calculation, the pacemaker with WPT secondary coil and a pacing lead is implanted in a sophisticated human body model.
