The Method of Sensory Evaluation of Humid Sense in Clothing
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.18 Vol.18】
We feel discomfort sense in summer and after exercise. This discom-fort sense is caused by high humidity. So Sensory Tests were done using circle patchs (Ф5cm) which were made in four kinds of terry towel. At the same time, finger blood flow was measured every 0.1 second.
Two methods were used for evaluation of the relation of the senses and finger blood flow. One is the summation of the every data of blood flow during humid stimulus. The other is the frequency analysis by FFT.
In case of the using of frequency analysis, subjects felt colder, wetter, more discomfortable, the slope of the frequency analysis was bigger.
In the future, we will be able to use the slope of frequency analysis of finger blood flow as the index of evaluating comfort sense.
