New Approaches For Augmented UHF RFID Textile Yarn

In the context of smart textiles, this paper addresses the evolution of the UHF RFID technology towards novel functionalities such as physical parameters sensing and tag' s integration with the identified object since the fabrication step. More precisely, the first part is dedicated to the presentation of physical parameters sensing such as temperature and humidity starting UHF RFID yarns. The second part of this paper deals with the design and the characterization of a helical antenna able to support elongation efforts and so offering a better integration with the textile wire.
