A proposal on wireless power transfer for medical implantable applications based on reviews

Since wireless power transfer technology (WPT) gains its popularity, broad range of application and research are performed in the field of medical implantable applications. In this paper, we review the technical status of WPT system applied to medical implant devices. As a practical application of this technology, the current achievements and challenges of wireless capsule endoscopy are reviewed and analyzed, in view of its design, functional requirement and related issues in WPT. And WPT application to artificial heart is also discussed. Based upon the analysis, we propose a research directions and WPT consideration in designing a WPT system for implantable medical applications.
