Design and optimization of inductive power transmission for implantable sensor system

This paper presents a methodology to design and to optimize inductive power link for biomedical applications. The importance of the operation frequency on the application is expressed. A model of inductive link is presented. The dimensions of the coils are compatible with the size of a mouse and the mouse cage. The simulation results are in good agreement with the analysis.
