Basic Study of Tactile Sensation and Skin Vibration on Sportswear
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.41 Vol.41】
ABSTRACT
The purpose of this study was to collect basic data for use in developing more comfortable sportswear through the study of skin vibration and tactile sensations. Skin vibration was measured when eight healthy young women were asked to run their fingers along nine types of sportswear material （including a control） in both high-temperature and low-temperature environments. The collected vibration wave data was then subject to an FFT analysis to determine vibration strength and median frequency. As a result of looking at skin vibration in response to （1） the physical properties of the material, （2） skin characteristics, and （3） sensory evaluations, we were able to indicate a variety of frequency characteristics in the skin vibration data and identified a high degree of correlation between the frictional characteristics of the material and skin vibration strength. In comparing the two environments, we found large variations in vibration strength in low-temperature condition and a tendency towards higher median frequency. Skin characteristics changed at low temperatures, which may have impacted the contact between the skin and materials. With the sensory evaluations, the study clearly demonstrated that the lower the vibration strength and the more low-frequency components were included in the vibration, the more readily the subjects felt smoothness, softness, and moistness; while the higher the vibration strength and the more high-frequency components were included in the vibration, the more readily they experienced roughness, stiffness, and dryness.
