ABSTRACT: Radio frequency identification (RFID) provides great potential for different Internet of Things (IOT) applications. In the future, material choices in these IOT devices will have a huge effect on the environment and thus use of renewable materials is a growing trend. In this paper, passive ultra high frequency (UHF) RFID tags were inkjet-printed directly on wood, paper, and cardboard substrates, and their performance was evaluated by measuring two key properties: threshold power and theoretical read range. According to our measurements, the tags on wood showed read ranges of 7 - 8 meters, the tags on cardboard exhibited read ranges of 4 - 7 meters, and the tags printed on paper showed read ranges of 2 - 7 meters through the global UHF RFID band. According to these results, the performance of these inkjet-printed UHF RFID tags is sufficient for many IOT devices and potential applications e.g. in construction and packaging industry.
