Simulation Research on Wireless Power Transmission System of Cardiac Pacemaker Based on Magnetic Resonance

Abstract

Abstract: Aiming at disadvantages of the battery limited supply time of the implantable cardiac pacemaker and the actual application of electromagnetic induction wireless power transmission (WPT) system, the resonant WPT technology was proposed. The basic working principle of a WPT system of the implantable cardiac pacemaker was introduced. Based on Magnetic resonance coupling and mutual inductance calculation model, the mathematics models of the WPT system of the cardiac pacemaker were established. By the accurate formulae of the mutual inductance of the primary and secondary coreless coils, the influences of the parameters, such as the axial distance, radial offset and coli radius, on the WPT performances were studied. And these results could provide an important theoretical guidance and reference for the design of the cardiac pacemakers coupling parameters and optimizing of the system performance.

Key words: wireless power transmission, resonance, magnetic coupling, cardiac pacemaker
