This study compares the feasibility of physiological signals acquired from wearable sensors to assess building occupants' thermal comfort. Field experiments were conducted to acquire electrodermal activity (EDA), heart rate (HR), skin temperature (SKT), and thermal comfort ratings from 18 subjects in actual office settings using wristband-type wearable biosensors based on thermal preference votes. Multilevel modeling outcomes indicate that (1) there are significant differences in electrodermal level (EDL) and SKT between the “Want Warmer” and “No Change” and between the “No Change” and “Want Cooler” states across subjects; (2) while the thermal comfort significantly affects subjects' EDLs, the effects are not significant on SKT after associations with other physiological signals are accounted for. Given the diversity of building occupants and environmental conditions, findings from the comparative analysis are expected to provide a foundation for the development of a general thermal comfort model using physiological signals.

腕带式可穿戴传感器生理信号评估乘员热舒适度的比较可行性研究

这项研究比较了从可穿戴传感器获取的生理信号来评估建筑物居住者的热舒适度的可行性。进行现场实验，使用基于热偏好投票的腕带式可穿戴生物传感器，获取 18 名受试者在实际办公室环境中的皮肤电活动 (EDA)、心率 (HR)、皮肤温度 (SKT) 和热舒适度评级。多级建模结果表明（1）不同受试者的“想要更温暖”和“无变化”状态以及“无变化”和“想要更凉爽”状态之间的皮肤电水平（EDL）和 SKT 存在显着差异；(2) 虽然热舒适度显着影响受试者的 EDL，但在考虑与其他生理信号的关联后，对 SKT 的影响并不显着。鉴于建筑居住者和环境条件的多样性，比较分析的结果预计将为使用生理信号开发通用热舒适模型奠定基础。
