Energy Harvesting in RFID Systems

Abstract

Energy harvesting for wireless sensors and RFID smart tags is a critical design feature on the path to the grand vision of ubiquitous computing. An important subset of energy harvesting solutions is the use of the RF reader signal to deliver energy and power up smart RFID tag circuitry. This paper focuses on the design of multi-stage voltage rectifiers and the power management strategies needed to power the large loads associated with sensors and microcontrollers integrated into the RFID tag
