 Review of wireless power transfer techniques and their classifications in biomedical applications.  Comparison of WPT methods for biomedical devices based on performance metrics.  Introduction to major near-field wireless power transfer topologies and related mathematical models.  Comparison of data transmission schemes in WPT-based modulation techniques.  Investigation of the main applications of biomedical devices, then discussion of the challenges and solutions.Bio-implanted medical devices with electronic components play a crucial role due to their effectiveness in monitoring and diagnosing diseases, enhancing patient comfort, and ensuring safety. Recently, significant efforts have been conducted to develop implantable and wireless telemetric biomedical systems. Topics such as appropriate near-field wireless communication design, power use, monitoring devices, high power transfer efficiency from external to internal parts (implanted), high communication rates, and the need for low energy consumption all significantly influence the advancement of implantable systems. In this survey, a comprehensive examination is undertaken on diverse subjects associated with near-field wireless power transfer (WPT)-based biomedical applications. The scope of this study encompasses various aspects, including WPT types, a comparative analysis of WPT types and techniques for medical devices, data transmission methods employing WPT-based modulation approaches, and the integration of WPT into biomedical implantable systems. Furthermore, the study investigates the extraction of research concerning WPT topologies and corresponding mathematical models, such as power transfer, transfer efficiency, mutual inductance, quality factor, and coupling coefficient, sourced from existing literature. The article also delves into the impact of the specific absorption rate on patient tissue. It sheds light on WPT's challenges in biomedical implants while offering potential solutions.
