Recently, a research team led by Associate Professor Rong Cancan from the School of Electrical Engineering of CUMT in collaboration with institutions including the National University of Singapore and Nanyang Technological University, published a review article titled "Magnetically Coupled Resonant Wireless Power Transfer for Internet of Things Perception Layer: A review" in the top-tier energy journal Renewable and Sustainable Energy Reviews (RSER, Impact Factor: 16.3).

The article systematically analyzes advances in the application of Magnetically Coupled Resonant Wireless Power Transfer (MCR-WPT) technology within the perception layer of the Internet of Things (IoT). It specifically focuses on the design and optimization strategies of High-Degree-of-Freedom (High-DoF) systems and Multi-Receiver Charging (MPC) systems, providing crucial theoretical references for advancing the practical implementation of wireless power supply technology for IoT devices.

Wang Haoyang, a 2023 graduate student from the School of Electrical Engineering, is the first author of the paper and CUMT is the primary affiliation.

The perception layer of the IoT, deploying billions of sensor nodes, serves as the "nerve endings" connecting the physical world to the digital space. However, the limited endurance of traditional batteries has become a core bottleneck hindering its large-scale application, particularly in scenarios like smart homes, industrial automation, and medical monitoring where frequent battery replacement is difficult. Wireless Power Transfer (WPT) technology emerges as a key solution. Compared to other WPT methods, MCR-WPT enhances energy transfer efficiency through resonance effects, offering both flexibility and stability within the near-field range. It is regarded as an ideal solution to support the continuous operation of devices in the IoT perception layer.

Renewable and Sustainable Energy Reviews (RSER), founded in 1966, is one of the highest-impact journals in the energy field. Its review articles are renowned for their in-depth analysis and forward-looking perspectives, playing a vital role in driving renewable energy technology innovation and the implementation of sustainable development strategies. This review article systematically integrates the research framework of High-DoF and MPC technologies within the IoT perception layer. By synthesizing nearly 200 cutting-edge publications, the study establishes for the first time a comprehensive theoretical system for MCR-WPT technology—spanning from the design of magnetically coupled mechanisms to system optimization—providing a key reference for the standardized application of near-field wireless power supply technology in IoT scenarios.
