Optimal design of inductive coupled coils for biomedical implants using metaheuristic techniques

Abstract

Powering implanted biomedical devices (IMDs) and sensors is a major obstacle for researchers in the microelectronics field. Such as the problem of miniaturization, increasing the distance between the external part (TX) and the internal part (RX), and the improvement of the power transfer efficiency (PTE), … The purpose of this article is to compare two strategies for optimizing component characteristics for a wireless energy transfer system (coupling of two coils), based on the new Figure-of-Merit (FoM) or iterative procedure (IP), and genetic algorithm (GA), in order to have a power transfer efficiency equal to 15% and 94.18 % respectively for a separation distance d = 12cm.
