Design And Manufacture

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.

Transmission Parameters

Magnetic resonance wireless power transmission uses resonance strong coupling between the transmission and receiving terminals to realize a non-contact efficient supply of energy over large distance. The transmission power, efficiency and distance are confirmed by comprehensive function of the transmission parameters. By taking experimental means, the influence laws of loop transmission parameters, such as separation between coils, coil size, etc., on the transmission performance are studied in this paper. The experimental results show that the power high-efficiency and high-quality transmission does not depend on the large coil loop coupling coefficient and transmission power and efficiency may increase firstly and then decline as the separation between coils increases. The transmission performance can be optimized by increasing the coils diameter or wire diameter, and moreover, transmission systems with a high resonance frequency can produce high power and efficiency transmission over short distances.
