The present application relates to a temperature detection device, in particular, to the field of temperature detection. The temperature detection device provided by the application includes: a heat absorption layer, a semiconductor column, a heat insulation layer, an insulation layer, a graphene layer, a first electrode and a second electrode; when the temperature detection device detects the external temperature, the heat absorption layer Absorb external heat and transfer the heat to the semiconductor column, so that the temperature of the short end side of the semiconductor column of the "T" shape structure increases, because the temperature of the long end of the semiconductor column close to the graphene layer does not change , then there is a certain temperature difference between the two ends of the semiconductor column, and then the carriers on the semiconductor column converge on the graphene layer, thereby changing the electrical conductivity of the graphene layer, by detecting the first electrode and the second The change of the electrical conductivity between the electrodes, and according to the corresponding relationship between the change of the electrical conductivity between the first electrode and the second electrode and the temperature to be measured, the temperature to be measured is obtained.
Description
technical field [0001] The present application relates to the field of temperature detection, and in particular, to a temperature detection device. Background technique [0002] Temperature is a physical quantity that expresses the degree of heat and cold of an object. Microscopically, it is the intensity of thermal motion of the molecules of an object. Temperature can only be measured indirectly through certain properties of objects that change with temperature. With the development of science, the accuracy of temperature measurement is getting higher and higher. [0003] In the prior art, an electronic thermometer is generally used to achieve relatively accurate temperature measurement, and the electronic thermometer uses a temperature sensor to measure the temperature according to the relationship between resistance and current. [0004] However, at different temperatures, the resistance of the electronic thermometer will change with the temperature, making the temperatu...
