RF Electromagnetic Energy Harvesting for Smart Sensors in Smart Communication Systems- A Review

Abstract

In the smart communication era, advancements in miniaturization technology have led to the development of RF energy harvesting due to the ambient/dedicated RF energy availability. It contributes to the realization of more sustainable, autonomous, eco-friendly, and efficient sensor nodes in the far-field communication links. The deployment of RF energy harvesting system is confronted with a number of obstacles, including power transformation efficiency, DC output voltage, and sensitivity. In this work, a detailed review of antenna design, impedance matching, and rectification efficiency are discussed for the development of an energy-efficient RF energy harvesting system.
