Abstract: In recent years, there has been a growing interest in wireless power transfer (WPT) that represents a promising technology for energizing low-power electronic devices. In this regard, particularly attractive is the use of WPT for recharging embedded devices, such as sensors for structural monitoring or implantable medical devices (IMD); in fact, these devices are difficult to access for the battery replacement or a direct connection to a power grid. More specifically, in the case of medical implants, the limited lifetime of the battery determines the necessity of periodically replacing the device through surgery. The use of WPT combined with a rechargeable battery could extend the lifetime of these devices up to 20 years, with obvious advantages for their users. According to these considerations, in the literature, several wireless power transfer methods and wireless links for either data or power transfer to medical implants have been discussed
