In this paper, we study the wireless response and reliability of graphene-based passive UHF RFID tags in high humidity conditions. The functional graphene ink is deposited directly on cardboard substrate to fabricate the RFID tag and the tag performance is evaluated through wireless tag measurements before and after high humidity conditions. Initially the peak read range of the tag is about 2.7 meters, which increases to 3.2 meters in high humidity conditions. Additionally, after drying, the performance of the tag returns back to normal. The results show that this low-cost and eco-friendly graphene RFID tag has a remarkable and unique response to moisture and has a strong potential to be used in future humidity sensor applications.
