A Literature Survey with the Focus on Magnetically Coupled Wireless Power Transfer Systems Developed for Engineering and Biomedical Applications

This project gives detailed instructions for designing, analyzing, and building magnetically coupled wireless power‑transfer (WPT) systems that are useful in biomedical and engineering work. Implantable medical devices and portable diagnostic tools need safe, wire‑free ways to receive energy. Magnetically coupled resonance and inductive coupling are now the main methods used for this purpose. The guide covers the basic electromagnetic ideas behind near‑field energy transmission, with special attention to: – coil shapes and sizes – matching resonant frequencies – achieving high power‑transfer efficiency It also describes how to create a low‑power prototype that can send wireless energy through simulated biological tissue. By testing the effects of distance, coil misalignment, and the

permittivity of the surrounding medium, the project provides a clear framework for optimizing transmitter and receiver coil designs. Safety issues are discussed, including specific absorption rate (SAR) limits and heat buildup in biological environments. Overall, this resource helps engineering students model, simulate, and build functional wireless‑charging modules, linking theory with real‑world biomedical device integration.
