Abstract
This manuscript presents a comprehensive study on the design of radio-frequency (RF) energy harvesting circuits tailored for low-power electronic devices, with all technologies and literature confined to developments. The abstract summarizes the motivation for RF energy harvesting as a means to extend the operational lifespan of battery-constrained sensors and wearable electronics. We outline the key contributions: the design methodology for matching networks and rectifier stages, statistical performance evaluation via a representative dataset, simulation-based validation using SPICE-level models, and identification of optimal design trade-offs. The results demonstrate that, with proper impedance matching and high-efficiency rectification, harvested power levels in the microwatt range can reliably power ultra–low-power sensors under ambient RF conditions typical of urban environments.
