Advancing Wireless Power Transfer A Comprehensive Review and Future Prospects

Abstract:

Wireless Power Transfer (WPT) is a transformative technology enabling energy delivery without physical connections. This review explores key WPT methods, including inductive coupling, resonant inductive coupling, capacitive coupling, microwave power transfer, and laser-based power transfer, highlighting their principles, efficiency, and applications. WPT is widely used in consumer electronics, electric vehicles, medical devices and industrial systems, offering a promising alternative to wired charging. However, challenges such as efficiency limitations, safety concerns, and distance constraints remain barriers to widespread adoption. Recent advancements, including improved efficiency, miniaturization, and integration with communication systems, are discussed, alongside emerging trends like long-distance WPT and renewable energy integration. The paper identifies critical areas for future research, such as safety protocols and economic feasibility, while emphasizing WPT’s potential for sustainable energy solutions. This review provides a concise overview of current technologies, applications, challenges, and future directions, serving as a valuable resource for researchers and policymakers in the field. This paper aims to provide a comprehensive review of WPT technologies, their underlying principles, and their applications across various sectors. By examining recent advancements and emerging trends, this study seeks to identify future research directions and highlight the transformative potential of WPT for sustainable energy solutions.
