Abstract
A capacitive type temperature sensor includes a first electrode layer, a second electrode layer, a dielectric layer positioned between the first and second electrode layers and having a dielectric of which a volume is changed in response to a temperature change, and a temperature calculation unit calculating a temperature corresponding to an electric potential difference between the first and second electrode layers. Accordingly, the capacitive type temperature sensor has a good sensitivity of measuring the temperature and a good accuracy, does not consume a large amount of power, and allows a process of fabricating the same to be simplified.
