We study 3D printing of graphene UHF RFID antennas on a thin wood veneer substrate, subsequently cured by heat in an oven or photonically by pulsed Xenon flash. We present the read range results of the tags and test the effects of moisture on the tag performance. Initially the peak read ranges of both types of tags are about 4.5 meters. The read range decreases about 50 cm when the tag antenna and...
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...
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,...
Due to the massive increase in the number of wireless devices, studying the use of cost-effective and environmental-friendly materials to be used together with effective additive manufacturing methods has been a growing trend in electronics during the recent years.

Graphene based nanomaterials open a new horizon in the electronic devices due to the unique and superior properties of graphene. The deposition of graphene based materials has significant effects on their final properties. Moreover, deposited graphene based samples are reduced by chemical or thermal reduction methods. To save time and energy compared to conventional approaches, advanced methods such...
Inkjet printing is one of the emerging methods for fabrication of electronic devices. The important issue in this area is developing nanomaterial-based inks for different applications such as gas sensors for environmental monitoring. In particular, graphene-based materials have recently gained interest due to their extraordinary properties. However, graphene has hydrophobic nature resulting in poor...
