We characterize a passive UHF RFID tag based on a stretchable dipole antenna which is screen printed on ultra-thin polyurethane substrate with silver ink. Our results show that the change in the conductor properties due to strain is large enough to modify the electromagnetic properties of the antenna notably, yet small enough so that the tag retains high performance even under 20-% strain. By comparing...
Electrically conductive textiles are an enabling technology for the future wearable healthcare. In this work, we investigate the impact of antenna-fiber alignment and recurrent stretching on the performance of passive UHF RFID tags based on screen printed and conductive-fabric antennas. Our results show that on the non-uniform fibrous textiles, the antenna-fiber alignment is an important factor for...
This paper presents an overview of various radio frequency identification (RFID) tag fabrication methods and briefly describes the advantages and disadvantages of each method. The purpose of this paper is to provide readers with the RFID fabrication techniques that can be applied in laboratory scale experiments. The performance results of laboratory made RFID tags based on two fabrication methods...
