- Abstract
- This article presents a macromodel-based electrical simulation model of a skin- implantable system, capable of transmitting RF power and data through an inductive link. This model makes it possible to assess the efficiency of energy transmission as a function of lateral and longitudinal displacements between the external coil (transmitter) and the implanted coil (receiver). This model must describe the behaviour of the mutual inductance in relation to lateral and longitudinal displacements. For that, a behavioural modelling was made on the basis of the mathematical equation of the mutual inductance. A polynomial interpolation of order four of this equation was established to lead to the electric model in the form of a sub circuit. This modelling made it possible to study and to simulate the efficiency and the impedance brought back to the entry of the inductive link in relation to lateral and longitudinal displacements. The power amplifier itself is a class E amplifier optimized in both output voltage and efficiency, and bears an excellent tolerance to displacements. © 2010 Praise Worthy Prize S.r.l.- All rights reserved.
