An Optimal Geometry for Power Energy and Data Transmission in the Inductive Link

This study presents the inductive link and the stability of the mutual inductance between various coils of different forms to guarantee a transfer of unidirectional energy communication between the implantables electronic devices. Study rested on the increase of the efficiency allocated by the tolerance to the lateral and longitudinal displacement between the external coil (transmitter) and the implanted coil (receiver). This study consisted in looking for the geometry of coils the least sensitive to the displacement and the most stable in mutual inductance. The mutual inductance was treated analytically by mathematical simulations using the Neumann equation for some geometries, to guarantee the maximum of power transfer energy in electronic systems implantables. This study treated the optimal geometry, the experimental measure of the mutual inductance for the energy transmission by various implantables systems in the human body.
