A Review of Wireless Charging Systems for Cardiac Pacemakers

Some of the advantages of wireless power transfer technology are reliability, safety and convenience of use, features suitable for biomedical applications. In recent years the implementation of these systems has increased due to improvements in technology and efficiency. This paper reviews the state of the art in wireless power transfer for cardiac pacemaker charging using inductive power technology with resonant converters. Resonance frequency, magnetic coupling or typical topologies are the most studied concepts by researchers in wireless charging systems for pacemakers. The compilation of authors and knowledge in this field provides an overview of the current status and allows further progress to be made in making this technology viable.
