Energy Acquisition Through Wireless Power Transfer

Battery-powered devices face unprecedented technical problems due to limits such as low power density, expensive, and heaviness. Wireless power transfer (WPT) is a revolutionary energization pattern that provides a completely new way for electric-driven devices to acquire energy, reducing their reliance on batteries. This study provides a review of WPT approaches, focusing on their working mechanisms, technical obstacles and traditional applications. This study focuses on WPT systems and highlights current important research areas as well as potential development trends. This unique energy transmission system has important implications for the widespread use of renewable energy in our daily lives.
