Implementation and performance evaluation of graphene-based passive UHF RFID textile tags

In this paper, we investigate the fabrication and wireless performance of graphene-based passive UHF RFID textile tags. Two different graphene-based inks were used to fabricate identical antennas on a fabric substrate by doctor blading technique. The performance of the tags was evaluated with wireless measurements throughout the UHF RFID frequency band. Based on our results, the graphene-based tags showed attainable read ranges of 1.6 and 2.4 meters. According to these first results, these tags have a great potential in future wearable applications along with cost-effective and eco-friendly aspects.
