Design and Fabrication of Embroidered RFID Antennas for Wearable Applications

Abstract

With advances in materials and fabrication methods, wireless communication devices are widely employed in Internet-of-Things (IOT) and human wearable applications. In this paper, we present a set of RFID labels using embroidered yarns that can be seamlessly integrated into clothing or textiles in fabrication processes. Detailed embroidery methods based on conductive yarns and textile substrates are proposed. The simulation and measurement results show that textile-based RFID antennas can provide stable electromagnetic performances and compete with the metallic counterparts.
