The Design and Manufacture of the Wireless Power Transmission System in the Cardiac Pacemaker

Abstract:

Generally the cardiac pacemaker is supplied power by micro battery, but the battery lifetime is limited, the Wireless Power Transmission (WPT) technology is a new method to supply power source for the cardiac pacemaker. Firstly the structure of the WPT system in the cardiac pacemaker were introduced. Then, Coupling transformer and rectifying and regulating circuit were designed. Finally, the test system of the WPT in the cardiac pacemaker was established, and the resonance frequency was 596 kHz, When the work frequencywas equal to the resonance frequency, the output power was maximal; when the input voltage of the primary winding was 5.8V, the voltage of the cardiac pacemaker may be up to 8.8V, which could effectively drive the cardiac pacemaker Record S, the results show the design is feasible.
