  • the structure of the sensor parts 100, 100a and the structure of the sub-sensor parts 210, 210a are similar to those shown in FIG. It is different from the temperature sensitive material 210. In this way, by providing a plurality of sets of sensor sections and sub-sensor sections, the set of sensor sections that respond first can be used as an advance warning function.
  • both the sensor section 100 and the sub-sensor section 200 are provided on the fixed section 400 and are visible.
  • three (or more) combinations of sensor sections 100, 100a, 100b and sub-sensor sections 200a, 200b, 200c may be provided.
  • the heat stroke detector according to the embodiment described above is an application of the continuous temperature detector of the present invention to the human body
  • the industrial application of the present invention is not limited to this.
  • the sensor unit 100 may be attached to a device whose operation at a constant temperature for a certain period of time (thermal runaway, etc.) is desired to be detected.
  • FIG. 23 it may be used to check whether the temperature of plants or the like has exceeded a predetermined temperature. In this case, it may be placed as is in a flower pot, soil, etc.
  • the continuous temperature detector 10 may be attached not only to the arm, but also to the ankle, the circumference of the body, the surface of the neck, etc., to detect heat stroke.
  • the sensor portion may be made of only a temperature-sensitive material and a thermally conductive material (configuration 1-1), or may be made of a temperature-sensitive material, a thermally conductive material, and a uniform heat-conducting material (configuration 1-2).
  • a temperature-sensitive material (configuration 2-1), a temperature-sensitive material and a thermally conductive material (configuration 2-2), a temperature-sensitive material, a thermally conductive material, and a thermally conductive uniform material (configuration 2-3) are used.
  • the sensor section it may be only the sensor section or a combination of the sensor section and the sub-sensor section (combination of the number thereof). Furthermore, a heat insulating part, a fixing part, or both may be combined.
