Clothing contact comfort based on electroencephalogram

The tactile comfort of clothing is an important factor affecting clothing comfort. In this study, the change rule of human electroencephalogram (EEG) induced by different tactile clothing stimuli was investigated, and the relationship between EEG indices and the tactile comfort of clothing was explored. Brain wave signals were recorded using EEG under three clothing-wearing conditions: normal, smooth, and suede-textured surfaces. EEG frequency-domain analysis techniques were used to examine how the participants’ brainwave activity changes with frequency under these conditions. The results demonstrated that the three garment types had different contact sensations and induced different EEG features when worn. Specifically, clothing in contact with suede-textured clothing exhibited the highest α-wave and lowest β-wave power, whereas normal-textured clothing showed the opposite trend. EEG power was observed in the frontal, parietal, and central brain regions when participants wore suede-textured clothing, followed by smooth-textured clothing, and then normal-textured clothing. The power spectral density peaked in the α-wave band for all three clothing types, with the highest peak energy for warm suede-textured clothing, followed by cooler smooth-textured clothing, and the lowest peak for normal-textured clothing. These findings reveal the neurophysiological mechanisms of clothing contact comfort and provided a scientific basis for clothing design and evaluation.
