Abstract

A biomedical power and communications system is currently under development for the purpose of continuously monitoring neural activity in ratswith epilepsy over a period of nine months. A closed loop system is employed that dynamically adjusts for optimalperformance across a variety of conditions, such as motion of the rat in its environment. The system is designed to deliver 250 mW to the implant wirelessly at 13.56 MHz power carrier over distances ranging from 1 cm to 25 cm.The total system efficiency is theorized to be at least 15%, which is consistent with current state of the art.The analysis and design of such a biomedically implantable system is discussed in detail and specific components are chosensuch that a prototype may be constructed in future work.
