This paper introduces a flexible UHF RFID sensor to detect food quality. This sensor is based on an interdigitated capacity included in a RFID antenna on which is deposited a layer of vegetal biopolymer. Thus, depending on the food spoilage, electromagnetic coupling between the capacity and the biopolymer is used to modulate adaptation coefficient between chip and antenna of the RFID tag. This study is validated by experimental measurements of RFID-sensor exposed to real food gas environment in the process of degradation.
