An In-Depth Analysis and Overview of Wireless Power Transmission Technologies Designed for Charging Portable Electronic Devices

Vincent Onos Okhueleigbe, Abiodun Yusuff Bello

Abstract

Wireless power transfer (WPT) systems have emerged as a transformative technology for charging portable electronics, offering convenience, efficiency, and flexibility. This comprehensive review explores the fundamental principles, advancements, and applications of WPT systems, focusing on their integration into portable electronic devices. The study examines various WPT techniques, including inductive coupling, magnetic resonance, and radio frequency-based methods, highlighting their strengths, limitations, and suitability for different use cases. Additionally, the review addresses key challenges such as energy efficiency, transmission range, safety, and standardisation while discussing recent innovations and future trends in the field. By providing a holistic perspective on WPT systems, this review aims to contribute to developing and optimising wireless charging solutions for portable electronics.
