Abstract
This paper is a study on the development of a sensor for measuring tactile sensation. First, the specific feelings on six sample underwear are collected though the semantic differential method. Next, The base of the sensor is an aluminum can, around which a rubber sponge layer, PVDF (Polyvinylidene Fluoride) film, a protective layer of acetate film and gauze are stacked in sequence. The sensor is set on rotation axis of the motor and covered with the measuring object. It is then turned to collect the tactile information of the same fabrics. The features on the collected data are then extracted by calculating the variance and the intensity of power spectrum density on medium frequency range of output signal. Comparison of the results shows that the PVDF sensor well describes the tactile perception of human.
