Temperature sensing device and temperature sensing underwear

The invention provides a temperature sensing device and temperature sensing underwear, and belongs to the field of temperature sensing. The temperature sensing device and the temperature sensing underwear can be used for measuring the temperature of the skin of the chest. The temperature sensing device comprises a first temperature sensor array set and a bearing mechanism, the first temperature sensor array set is distributed in a first fan ring shape, the radial width of the first fan ring shape is 7 cm, and the argument of the first fan ring shape is 122 degrees. The bearing mechanism is constructed to bear the first temperature sensor array set. The temperature sensing device is used on the chest of a woman, the high-probability attacking area, related to temperature, of the chest can be fully covered, and therefore corresponding body temperature change information is collected.
