Wireless Power Transfer (WPT) with inductive coupling is the one most advanced techniques for powering biomedical implants, in recent decades has been the transmission of energy without the need of cables. The importants elements (indicators), power transfer efficiency (PTE) and power delivered to load (PDL), of a wireless power transfer systems . These keys are dependent on several design parameters of WPT system, such as the geometrical parameters of the coils, the separation of the sender (TX) and the receiver (RX). And also the operating frequency. The invention, design, and optimization of coils square spirals in a wireless energy transfer system using a resonant inductive link are the emphasis of this paper. Metaheuristic algorithms are among the optimization techniques used.
