    • PROBLEM TO BE SOLVED: To provide a sensor device that is highly sensitive and has a detection capability with a wide dynamic range, and enables sensing information to be taken out as a voltage signal.SOLUTION: A complementary circuit is configured of first through four same channel type transistors Tr1 through Tr4, and at least any one transistor of the transistors is constituted of an organic TFT to be used as a sensor element. The organic TFT to be used as the sensor element fulfills a function in which an electric characteristic varies by being subjected to a physical change or by absorbing a specific substance, and the other transistors constituting the complementary circuit is constituted to have no sensor sensitivity. Since the sensor device configures the complementary circuit, a detection capability with a wide dynamic range can be imparted, and since a sensor output is output as an electric voltage, the complementary circuit can contribute to a simplification of an external circuit constitution.

    • PROBLEM TO BE SOLVED: To provide an RFID label that destroys an IC chip and cannot be re-used when the RFID label is peeled off from an object to be stuck.SOLUTION: A flexible RFID is used which comprises: an IC chip 3 included in an RFID circuit, the IC chip 3 being formed by laminating the chip on a flexible substrate 1; and an antenna pattern 2 formed on the flexible substrate, the antenna pattern 2 being connected to the RFID circuit. An adhesive layer 8 is formed on one surface of the flexible RFID so that the flexible RFID can be stuck to the object, and an RFID circuit in the IC chip is destroyed when the flexible RFID is peeled off from the object. For example, a fluorine-based polymer material is preferably used for a TFT gate insulating film included in the IC chip 3, so that an adhesion force between the gate insulating film and an organic semiconductor layer is formed to be weaker than an adhesion force of the adhesive layer 8.
