Abstract
The present paper is concerned with the development of a haptic sensor that evaluates the human skin conditions. The base of the sensor is an aluminum shell, around which a rubber sponge layer, PVDF film, a protective layer of acetate film and gauze are stacked in sequence. The sensor is attached on to the tip of an elastic cantilevered beam and pressed against an the surface of the skin. It is then slid over the skin to collect the surface morphological features. Characteristics of data are examined by calculating the variance and the power intensity ration over several segmented frequency ranges. The sensor is applied to seeing the variation of skin conditions depending on ages.
