Flexible and Semi-transparent Chipless RFID Tag based on PDMS-Conductive Fabric Composite

This paper presents a 6-bit 25 mmx25 mmx0.4 mm chipless RFID tag based on square ring resonators. The tag is designed and developed using polydimethylsiloxane (PDMS) and conductive fabric composite, resulting in a flexible, semitransparent, and biocompatible chipless RFID tag, which is suitable for the unobtrusive modern wireless identification and monitoring systems. The tag data is decoded using the monostatic Radar Cross Section method. The tag design is validated with free-space measurements showing a good agreement with simulated results.
