Reconfigurable Intelligent Surfaces for Wireless Energy Transfer in IoT: A Survey on Architectures, Applications, and Open Challenges

Radio-frequency wireless energy transfer (RF-WET) has emerged as a promising solution for extending the lifetime of energy-constrained Internet of Things (IoT) devices, particularly in large-scale, obstructed, and hard-to-access deployments. However, practical RF-WET systems are limited by severe propagation losses, bl...
