| Popis: | Titanium cases are usually used as the main enclosure of implantable medical devices (IMDs), such as pacemaker. Different titanium alloys with different resistivities exist. Currently, the wireless powering of such IMDs is a challenging research topic. In this work, the influence that different titanium alloys have on the wireless power transfer link is studied at 13.56 MHz. It is shown in simulations and measurements, that a worst resistivity for the case of the implantable medical device exists, which minimizes the link efficiency. A simplified analytical model is also presented to understand this effect. Additionally, we show that titanium grade 2, which has a lower resistivity (better conductor) than titanium grade 5, achieves higher link efficiency than the grade 5, in our design at 13.56 MHz. Therefore, this analysis proves that the titanium alloy electrical characteristics should be carefully considered in the design of the wireless power transfer link. |
