Abstract
Neuromodulation is a treatment method, which aims to improve symptoms by stimulating abnormal nerve functions by using electricity or magnetism. Recently, implantable medical devices have ganered a great deal of attention as a method for neuromodulation, where devices are implanted both inside or outside the body for diagnosis, monitoring, and treating disease purposes. However, issues related to battery life and possible malfunctions from the battery usage, as well as issues from the angular and positional misalignment arise from the direct placement of a device inside a living body. In this study, we focused instead on implantable medical devices that use wireless power transmission and investigated a method by using multiple implantable communication terminals without batteries. As we assumed the developed device was used within the human body, we designed receiver coils considering the effects on the human body and conducted experimental evaluation of a neurostimulation device. In addition, a method to improve the receiving range when using multiple receiver coils was proposed and experimentally evaluated.
