Implantable medical devices such as pacemakers, implantable cardioverter defibrillators, deep brain stimulators, retinal and cochlear implants are gaining significant attraction and growth due to their capability to monitor the health condition in real time, diagnose a particular disease, or provide treatment for a particular disease. In order to charge these devices, wireless power transfer technology is considered as a powerful means. This eliminates the need for extra surgery to replace the battery. In this chapter, some of the major implanted medical devices are reviewed. Then, various wireless power transfer configurations are reviewed briefly for charging such devices. The chapter continues with reviewing wireless power transfer configurations based on the multi-layer printed or non-printed planar spiral coils. At the end, some of the recent works related to using multi-layer planar spiral coils for safe and efficient powering of IMDs will be discussed.

Wireless power transfer (WPT) systems have become increasingly suitable solutions for the electrical powering of advanced multifunctional micro-electronic devices such as those found in current biomedical implants. The design and implementation of high power transfer efficiency WPT systems are, however, challenging. The size of the WPT system, the separation distance between the outside environment and location of the implanted medical device inside the body, the operating frequency and tissue safety due to power dissipation are key parameters to consider in the design of WPT systems. This article provides a systematic review of the wide range of WPT systems that have been investigated over the last two decades to improve overall system performance. The various strategies implemented to transfer wireless power in implantable medical devices (IMDs) were reviewed, which includes capacitive coupling, inductive coupling, magnetic resonance coupling and, more recently, acoustic and optical powering methods. The strengths and limitations of all these techniques are benchmarked against each other and particular emphasis is placed on comparing the implanted receiver size, the WPT distance, power transfer efficiency and tissue safety presented by the resulting systems. Necessary improvements and trends of each WPT techniques are also indicated per specific IMD.
