Special Issue Information
Dear Colleagues,
Since Tesla's pioneering work in the late 19th century, wireless power transfer (WPT) has evolved from a conceptual innovation into a rapidly advancing field with a wide range of practical applications. The widespread adoption of portable electronics and implantable medical devices in the 21st century has revitalized interest in WPT systems, positioning them as essential technologies for modern applications where physical connectors are impractical or undesirable.
While WPT offers significant advantages in terms of portability, safety, and convenience, it faces inherent challenges in power conversion efficiency (PCE) and voltage conversion ratio (VCR) compared to conventional wired power systems. Current research focuses on coil-couple modeling and analysis, resonant circuit topologies optimization, resonant frequency calibration, power delivery distance/efficiency improving, single/multiple output regulation rectifier design, positive/negative outputs design, bidirectional WPT topology design, data link design on power link, etc. Despite these advances, WPT systems still face limitations relating to energy loss, thermal management, electromagnetic compatibility (EMC), and power scaling. Future prospects include enhancing the reliability and durability of WPT in medical implants and exploring high-power applications through novel materials and resonant architectures.
This Special Issue aims to present cutting-edge research and comprehensive reviews addressing these challenges and outlining future pathways for WPT technology.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
