| Research Abstract |
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 and we proposed the method to check the battery situation of rechargeable cardiac pacemaker by estimating the value from outside the body.
When the titanium case is not located between the primary coil and the secondary coil, we have confirmed that it is possible to estimate the secondary impedance value by using our proposed formula. We analyzed the effect of the titanium case and we proposed the estimated new our formula which inserted the titanium loss resistance. When the titanium case is located between the primary coil and the secondary coil, we have also confirmed that it is possible to estimate the secondary impedance value by using the new proposed formula.
