Design of Wireless Power Transfer for Heart Assist Devices

Abstract

Heart assist devices are designed for helping damaged hearts maintain sufficient blood flow, for patients getting heart attack with short term and it is used for congestive heart failure patients. The frequency with which the patients are being operated to replace the battery of these devices can be aided and reduced by wirelessly transmitting power. The transcutaneous power transfer for the devices requires charges that move outside the body to induce charges to move inside the body which can ultimately be used to supply energy to the heart pump. WPT is a method of transmitting wireless power using an external primary coil to generate a magnetic field. It passes through the skin and induces current in an implanted secondary coil. The infection caused due to surgery is removed by WPT method. To monitor the charging level of the battery the Wi-fi module is used. It also monitors the corresponding blood flow and the pulse during this function.
