サーミスタで計測した外耳道温を用いた深部体温算出のための校正について検討

The ear canal temperature measured using thermistor has the potential to be the available as core body temperature using the earphone in the outdoor exercise. However, the ear canal temperature effected of ambient temperature. The core body temperature measurement need to calibration. The dual-heat-flux method is one of the calibration method. Therefore, the aim of this study is to calculate core body temperature from the ear canal temperature based on the dual-heat-flux method. We measured the eardrum (reference), ear canal (inner ear air and inner ear surface) and near ear temperature in 10 healthy male participants. The core body temperature was calculated from the ear canal and near ear temperature. The result showed that the calculated temperature of some participants was closer to the eardrum temperature than the ear canal temperature. In conclusion these finding suggest that the core body temperature calculated from the ear canal temperature measured using thermistor might be used in the outdoor exercise.
