本研究旨在评估胸上区域贴片式传感器的可靠性，该传感器使用双热流通量方法来估计各种热条件下的核心温度。使用该贴片实时监测预测核心温度（Tpre），测量参与者的食管和直肠温度（Teso和Trec）。21名穿着工作服的志愿者和9名穿着防护服的志愿者在35摄氏度的温度下步行（5.0公里/小时）一小时。在运动过程中，两组的Teso分别增加到37.9 +/- 0.3摄氏度和38.2 +/- 0.2摄氏度。在每种服装条件下，Teso和Tpre的均方根误差（rmse）分别为0.18 +/- 0.05℃和0.25 +/- 0.08℃，Trec和Tpre的均方根误差分别为0.31 +/- 0.10℃和0.34 +/- 0.11℃。此外，11名志愿者在30摄氏度或40摄氏度的环境下步行一小时，运动时的Teso分别增加到37.7 +/- 0.3摄氏度和38.2 +/- 0.3摄氏度。在各环境温度条件下，Teso和Tpre的rmse分别为0.23 +/- 0.10℃和0.18 +/- 0.05℃。此外，8名志愿者在35摄氏度下进行了30分钟的摇臂运动（60瓦），运动期间Teso升高到37.9±0.2摄氏度。Teso和Tpre的rmse为0.22±0.07℃。所有成对测量值相差小于预定义的有效性阈值的比例
This study aimed to evaluate the reliability of a patch-type sensor on the upper chest region that uses a dual-heat -flux method to estimate core temperature under various heat conditions. The participants' esophageal and rectal temperatures (Teso and Trec) were measured with real-time monitoring of predicted core temperature (Tpre) using the patch. Twenty-one volunteers wearing work clothes and nine volunteers wearing protective clothing walked (5.0 km/h) for an hour at 35 degrees C. During exercise, Teso increased to 37.9 +/- 0.3 degrees C and 38.2 +/- 0.2 degrees C for each group, respectively. The root mean squared errors (RMSEs) were 0.18 +/- 0.05 degrees C and 0.25 +/- 0.08 degrees C between Teso and Tpre and were 0.31 +/- 0.10 degrees C and 0.34 +/- 0.11 degrees C between Trec and Tpre in each clothing condition, respectively. In addition, 11 volunteers walked for an hour at 30 degrees C or 40 degrees C. The Teso during exercise increased to 37.7 +/- 0.3 degrees C and 38.2 +/- 0.3 degrees C, respectively. The RMSEs were 0.23 +/- 0.10 degrees C and 0.18 +/- 0.05 degrees C between Teso and Tpre in each ambient temperature condition, respectively. Furthermore, eight volunteers performed an arm-cranking exercise (60 W) for 30 min at 35 degrees C. The Teso increased to 37.9 +/- 0.2 degrees C during exercise. The RMSEs were 0.22 +/- 0.07 degrees C between Teso and Tpre. The proportions of all paired measurements differing by less than the predefined threshold for validity of
