In recent years, there is a significant increasing in the demand for biomedical plants. Research shows that a larger number of Australians require implantable biomedical devices every year such as pacemakers, Cochlear implants and cardiovascular implants. Figures indicate that the number of pacemakers sold in Australia was 12523 in 2009. However, the number reached 15203 in 2013 with an annual increasing rate of 4.28%. However, most of the implantable devices remain restricted due to certain constraints. The power supply is one of the dominating factors that limits the use of biomedical implants because such devices need to function at a stable, efficient and reliable rate for a periodof time (normally for years). Currently, batteries are mostly used for powering implantable devices; however, it cannot be a desirable solution due to its short-comings such as size, the risk of infection and need of replacement. Consequently, this project aims to develop a wireless charging system that can be implanted into the human body with no need of replacing the battery. This project will define and quantify the tradeoffs between power requirement, lifetime and functionality for such systems. This document presents the outcomes of this project highlighting the problems encountered and solutions devised.
