Title:
The sensor device using an organic thin film transistor
Document Type and Number:
Japanese Patent JP6128378
Kind Code:
B2
Abstract:
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 sensor device constitutes a complementary circuit composed of a P-type transistor Tr1 and an N-type transistor Tr2, and at least one of the P-type and N-type transistors is composed 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 another transistor constituting the complementary circuit is constituted to have no sensor sensitivity. Since the sensor device constitutes the complementary circuit, a detection capability with a wide dynamic range can be imparted, and since a sensor output is output as a voltage value, the complementary circuit constitution can contribute to a simplification of an external circuit constitution.
