Basic Study of The Skin VibrationCaused by The Contact of Clothing with Skin

Abstract

In wearing clothes, passive contact between the clothes and the skin occurs accompanied with human movements. In this study, we first examined the contact between clothing and the skin on the trunk during the movement of upper extremity utilizing a pressure measurement film. It was clarified the neck, shoulder tip, and scapula are prominent contact sites. Next, we explored the possibility of skin vibration measurement in the vicinity of the protruding part of the scapula. Investigation of the vibration intensity and median frequency of the skin vibration caused by contact between the skin and clothing revealed that a site about 2 cm away from the contact area was suitable for measurements. In addition, from the skin vibration measurement in wearing several types of sportswear, it was clarified that the vibration intensity was greater in wearing sportswear than in not wearing it, and we found a certain tendency from the analyses of results of each sample. The relationship between the feeling of wearing and skin vibration is different from the active contact by tracing the clothing materials. In the passive contact between worn clothes and the skin, it was manifest that multiple factors, such as the looseness of the clothes and the characteristics materials, affect the skin vibration in contact.
