습도 변화에 따른 뇌파 기반 생체신호 변화에 관한 연구

Abstract

Subjects with 0.7[clo]'s amount of clothing were estimated on their thermal comfort, concentrativeness, heart rate variability, stress and fatigue degree when given variation in relative humidity to 30, 40, 50, 60, 70, and 80[RH%], in an environmental test room of temperature 25[℃], illumination 1000[lux] and air velocity 0.02[m/sec], by using EEG,learning ability and HRV. At the result, it was at 50∼60[RH%] of relative humidity that subject's thermal comfort and concentrativeness were at the highest while stress were at the lowest, and it was at 60[RH%] of relative humidity that heart rate variability was most stabilized. It was found that when temperature and humidity of the environmental test room are at 25[℃] and 50∼60[RH%], subject's productivity and psychological state are least affected.
