Abstract

This paper presents a wireless power transfer (WPT) system for powering internal pacemaker. A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate. The battery in the pacemaker lasts five to eight years or longer. When the battery runs down, surgery is needed to replace it. This paper provides a way of using rechargeable batteries for the pacemaker thereby avoiding frequent surgery. Based on a generic transcutaneous transformer model, a remote power supply using a resonant topology for use in artificial hearts is analysed and designed for easy controllability and high efficiency. There is a transmitter section and a receiver section in this process. The receiver section is placed in the patient along with the pacemaker. When the charge of the battery goes down, the transmitter section is placed nearer to the patient and thus recharging takes place. This proposed scheme allows a compact, efficient, and robust wireless power system. It has a efficiency of 70% . Index terms - wireless power transfer (WPT), internal pacemaker, rechargeable battery.
