Abstract

Implantable medical devices will play an important role in modern medicine for preventive and post-surgery monitoring, drug delivery, local stimulation, and biomimetic prosthesis. To reduce the risk of wire snapping, and replacement and corrosion of embedded batteries, wireless delivery of energy to these devices is desirable. Current studies in wireless power transmission into biological tissue tend to operate below 10 MHz because of the common belief that lower operating frequency yields higher power transfer efficiency.
