Abstract: This paper is a study on development of a sensor system for measurement and valuation of human touch feeling. The objects measured are underwear, knitwear, sample underwear and polo shirts with total 26 sheets. First, the tactile feelings of several fabrics were/touch valued by using the paired comparison semantic differential method handed onto 5 subjects. Next, a soft tactile sensor made of a PVDF (Polyvinylidene Fluoride) file patch and rubber layers is assembled and slid over the same sample fabrics to collect the surface tactile information. The features on the collected data are then extracted by calculating the variance of output signal and the intensity of power spectrum density on medium frequency range. Comparison of the results shows that the PVDF sensor well describes the human touch feeling.
