Resistance of metal depends on temperature. Therefore, the metal can be used as a temperature sensor with a reference resistor. The reference resistor is connected serially and the voltages of the sensor metal are measured after applying DC voltage. However, it is not easy to keep the reference resistance constant while measuring temperatures. We studied the temperature dependence of resistance of oxide material to apply it to the bridge type temperature sensor which is insensitive to the environmental temperature. We made bridge type temperature sensor with oxide material and metal. The novel temperature sensor does not need a reference resistor, and composed of oxide and metal. Therefore, we could remove error induced by environmental temperature variation. Moreover, the novel bridge type temperature sensor provides higher sensitivity than conventional sensor structure. By different thermal coefficient of the oxide material, it was possible to remove an external reference resistance. The proposed bridge type temperature sensor is a self-reference temperature sensor which is insensitive to the environmental temperature.

Thin‐film devices are widely utilized for flat‐panel displays, and the essential advantages of the thin‐film devices are generally large‐area production, various‐material substrate, layered structure, etc. Appropriate applications are flat‐panel displays, and other applications where the abovementioned advantages are available and the disadvantages are acceptable are sensor applications. Moreover, if the sensor devices can be made by thin‐film devices that have been already utilized for flat‐panel displays, they can be made without additional cost. Therefore, thin‐film devices are again promising for sensor applications especially for interactive displays. We are investigating sensor applications of thin‐film devices. Particular in this journal paper, we review sensor applications of thin‐film devices originating in display technologies. The various sensors are visible‐light sensor, infrared‐light sensor, temperature sensor, magnetic‐field sensor, etc. Many research results from many research organizations as well as our research laboratory are introduced.
