This paper is concerned with the development of a sensor system for monitoring skin roughness. The base of the sensor is an aluminum shell, around which a sponge rubber layer, a PVDF film layer, a protective surface layer of acetate film and gauze are stacked in sequence. The sensor is attached onto the tip of an elastic cantilevered beam and pressed against a human skin surface. The beam is then slid over the sample to collect the information on the object through the sensor. The features on the data are extracted by calculating both the variance and the intensity of power in the several frequency rages. Experimental results show that the present sensor system works well as a haptic sensor for monitoring the variations of human skin conditions depending on the aging.
