Wireless Power Transfer Design For Small Implantable Medical Devices

Last few decades has shown tremendous interest and growth in wireless technology. It was Tesla’s dream to trasnfer power wirelessly from one end to other end of the world. Until few decades back it was a topic of interest for few. But this days even major and high tech companies have drawn their attention towards this technology. Apple, Samsung are few of the companies to name who wants to use wireless charging technique for their portable devices. With this work we have tried to explore this wireless technology using magnetic resonance coupling for health care such as implantable devices. The main focus was to start a project to design a receiver that can charge implantable devices such as pacemaker wirelessly. Imagine a patient who doesn’t need to undergo heart surgery just to replace batteries for pacemaker, this would turn out to be a boon for humanity. The work has been carried out using software design tool HFSS and also hardware was designed accordingly. Simulation and real time measurements were carried out on pork muscle and compared. Simulation and practical measurements showed close proximity to a greater extent.
