Design and Development of a Novel Paper-based Inkjet-Printed RFID-Enabled UHF (433.9 MHz) Sensor Node

In this paper, inkjet-printed RFID-enabled sensor modules are investigated for the first time on paper-based substrates for UHF sensing/monitoring applications. An inkjet-printed antenna using silver nano particles on paper substrate is presented and utilized for the compact implementation of the wireless part of the node. The efficiency of the modulation scheme of the sensor signal is characterized at the UHF RFID Band operating around the center frequency of 433.9 MHz, verifying the feasibility of the sensor/rfid integration. Such low-cost integrated sensing nodes would enable the deployment of large ad-hoc wireless sensor networks that would mark a revolution in wireless automatic identification and real-time monitoring for medical, inventory and security applications.
