Abstract:
In this paper, research progress on wireless powering of implantable devices is discussed and summarized. An efficient method of powering of medical implants is a key component for receive progress in dramatic size reduction without traditional implant's limitation of a short battery life. Appeared in recent years publications reports possible ways of using of decimeter size radio waves (midfield powering) as a very efficient method versus near-field inductively coupling power transfer. But proposed frequencies in GHz range are unpractical due to existing regulations in national and international Radio frequency spectrum regulations, making impossible or very hard following certifications. This article review possible using of GSM or ISM band frequency as a basic frequency for powering of medical implants. Review of possible application in development of commercial available modules for wireless powering was done.
