Effect of Environment on Variability of Skin Resistance in Vehicle Interior

Abstract This study explores the relationship between ambient temperature and skin resistance in a vehicle cabin during winter. Using 1 Hz sensor data collected from four participants in Škoda Kodiaq, key environmental factors, including temperature and comfort features, were analysed. Strong negative correlations (up to -0.88) were found between skin resistance and temperature, especially near the body or airflow sources. The physiological response was nonlinear, with faster reactions to cooling. Heated seats influenced skin resistance trends, while particulate matter had no effect. The results suggest skin resistance as a potential indicator for thermal comfort and adaptive climate control.
