| Popis: | This work outlines a new approach for modifying conventional RFID tags with chemically sensitive conductive composites. Conductive composite films were integrated into the RFID tag circuit. As the film was exposed to selected analytes the film swelled increasing the resistance of the film and decreasing the communicating ability of the RFID tag. Using maleic anhydride as the sensing material, the composite was able to detect different biogenic amines associated with food spoilage. RFID tag response was found to depend on amine concentration, tag initial resistance and type of biogenic amine. RFID sensors of this nature are attractive for a number of applications in the gaseous sensing industry. |
