In this paper, a sensor system for evaluating tactile feelings of scalp hair is developed. A sensor with concentric circles shape projection which imitates fingerprint was mounted on a beam that was fixed to a linear slider. A Polyvinylidene Fluoride (PVDF) film was used as a sensory part. The sensor output was obtained by contacting with the measuring object and scanning on it. Three parameters that are expected to have correlations with tactile feelings were calculated by signal processing of sensor outputs. Evaluation of human hair has problems due to randomicity and difficulty of putting them uniformly without overlapping. Therefore, a plate imitating the physical and chemical properties of human hair surface was used as measuring objects for stable measurement. The plates cleaned down with several kinds of treatment were measured by the sensor and human sense. By comparison between sensor outputs and sensory evaluation, it is confirmed that the sensor system can discriminate the treatment effects. The results suggest that these factors could be evaluated by the sensor system.
