This study aims to accurately present the bioelectrical impedance (BI) as a significant physiological variable to accurately determine thermoregulation and complement thermal sensation questionnaires. A series of environmental chamber tests were conducted. At the same time, the indoor temperature fluctuated between 20◦C and 40◦C, skin BI of the body area was measured in conjunction with skin temperature and comfort survey. The room temperature was controlled while the BI was monitored on the wrist (back), contrasting with the usual methodology for determining thermal comfort. Skin BI on the wrist (back) directly correlates with thermal comfort. The bioelectrical impedance of the skin can be used as an additional variable to identify the inhabitant’s response to space and determine thermal comfort. Measurements of heart rate, wrist temperature, forehead temperature, relative humidity, and bio-impedance, taking ambient temperature as independent variable are contained in the file.


Steps to reproduce

A protocol experiment was conducted with human subjects to collect local skin temperature and BI measurements from their posterior forearms. The study was performed in February 2018 with 17 volunteer participants from Universidad de Colima.
