Experimental study on antenna — IC interconnections for electro-textile RFID tags

Wearable passive UHF RFID tags have enormous potential in future body-centric wireless communication and sensing systems, which have countless applications for example in the welfare and health care sectors. Antenna-IC joints in these wireless components are usually the critical parts from the reliability point of view and they operate in an extremely challenging environment. In this study, we demonstrate the wireless performance and reliability of three types of textile RFID tags with the antennas patterned from commercial electro-textile materials and the ICs attached with two different electrically conductive adhesives. Based on our results, the major reliability challenge is to find a suitable conductive adhesive to be used with each different electro-textile material.
