Impact of antenna-fiber alignment and recurrent stretching on the performance of passive UHF RFID tags based on textile antennas

摘要

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 the performance of the tag and its response to repeated stretching. Moreover, the tags fabricated with the two different methods were found to exhibit contrasting features in their response to the stretching.
