Simulative and experimental research on wireless power transmission technique in implantable medical device.
As the development of implantable biomedical devices, the rechargeable battery is applied to improve the life of implantable devices. Inductive transcutaneous power transfer, as a suitable way of charging the implantable rechargeable batteries, is widely used. During charging period, there are several stages based on the charging rule and the load resistance is varying simultaneously. In this paper, a model of inductive transcutaneous power transfer is set up with a compensative capacitor for primary coil in series and another compensative capacitor for secondary coil in parallel to descript the relationship in coupling coefficient, load resistance and conversion efficiency. Simulations were done and experiments were carried out to verify the model, and some suggestions on wireless power transfer design are given.
