Optimal configurations of multi-transmitter wireless power transfer systems for biomedical implants

As the technology of modern medicine continues to move forward, an increasing emphasis will be placed on smart electrical biomedical implants. With various advances already made over the past years, these technologies are still restricted by the size and weight of the battery used, as well as its required replacement at the end of its life. An emerging alternative is to consider wireless power transfer (WPT) to operate or recharge biomedical implants in place (in vivo), thereby eliminating the aforementioned issues. While the characteristics and optimization of single-transmitter WPT systems in free space have been well-established, the same problem in a medium of biological tissue, and when considering multiple transmitters, is not yet understood to the same degree.
