Abstract
An ostomy appliance includes a substrate and at least one Radio Frequency Identification (RFID) circuit disposed on the substrate. The RFID circuit includes a RFID transponder having an antenna and a conductive ink connected in series with the antenna and the RFID transponder. The conductive ink is configured to dissolve in response to exposure to moisture. The RFID circuit is in a closed condition when the conductive ink extends continuously between the RFID transponder and the antenna. The RFID circuit is in an open condition when at least a portion of the conductive ink is dissolved.
