The recent advances in MedTech have seen an interest for accurate modeling and high-precision simulations in order to characterize and predict the behaviour of medical devices employed in various applications. My presentation will focus on the analysis of modeling using three-dimensional simulations of medical electronic devices such as cochlear implants and insulin pens. To this purpose ANSYS simulator has been used in HFSS and Maxwell 3D modules respectively. Firstly, to characterize the antennas in cochlear implants a multi-tissue model has been prepared and high-frequency analysis has been performed providing amongst other radiation patterns, Smith charts and contour plots of the total radiated field. Secondly, a three-dimensional model for the capacitive measurement in an insulin pen used by diabetic persons has been studied, where a fully parametrized model allowing for capacitance evaluation has been proposed. In the latter case, a multi-electrode configuration for a real-life insulin pen has been investigated.
