Abstract
Broader contextSince Tesla proposed the concept of wireless power transfer (WPT) in 1880s, WPT technology has transitioned from communication to energy transmission after more than 100 years of exploration and development in electromagnetics. It has gradually entered people's daily lives and industrial scenes, providing a convenient and flexible power supply for consumer electronics devices and industrial electronics applications. Since the beginning of the 21st century, with the increasing demand for electricity and the growing importance of energy management, WPT technology is expected to have huge potential and application value. This technology utilizes various methods such as magnetic fields, electric fields, microwaves, and lasers to achieve energy transmission under different high frequencies of electromagnetic waves. It has been extensively explored and demonstrated in various fields, such as consumer electronics, electric vehicles, implantable medical devices, solar space power stations, and aerospace; however, it still faces numerous challenges in practical applications. Therefore, this paper provides a detailed review of the physical mechanisms and resonance theories of WPT technology, performance enhancement methods, application scenarios, and future research directions, aiming to provide a comprehensive reference for relevant practitioners and researchers to promote the various applications of WPT technology in modern technology fields.AbstractThis paper provides a comprehensive overview of recent advancements, challenges, and potential applications of wireless power transfer technology. It covers various aspects of wireless power transfer, including magnetic-filed coupling, electric-filed coupling, microwaves, and laser technologies. The paper sheds light on physical mechanisms, current state-of-the-art techniques, their limitations, and the prospects of this rapidly evolving field, with a focus on both theoretical developments and practical implementations. This review aims to contribute to the understanding and advancement of wireless power transfer systems for diverse applications in the modern technological landscape. This paper discusses not only the field of wireless power transmission that has already been applied, such as wireless charging of electric vehicles, consumer electronics, implantable medical devices, and underwater equipment, but also applications that are still under research such as space microwave transmission, large-scale free space energy transmission, and roadway-powered electric vehicles.
