Outline of Final Research Achievements

We have been researching the rechargeable cardiac pacemaker. It is difficult to estimate the charge situation from outside the body. We focused on the secondary impedance value which changes according to the charge status. We proposed the method to check the charge situation by estimating the secondary electric parameters from primary ones of outside the body.
In this study, we verified the estimated method of several secondary electric parameters from primary ones of the outside the body. And we focused on rectangular waves drive that can be made easier than sine waves drive to reduce the size and cost. We verified the secondary impedance estimation in wireless power transfer using the square wave drive.
