Abstract
This paper is a study on the development of active haptic sensor system for monitoring human hair under dry and wet conditions. The polyvinydene fluoride (PVDF) film, which is a kind of piezoelectric materials, is used as the sensory receptor. The sensor consist of a silicone rubber, a PVDF film, and a projection for the contact to objects. The sensor output is obtained by contacting and scanning of the sensor on the object. Evaluation using human hairs has problems due to randomicity, and difficulty of putting them uniformly without overlapping. Therefore, in this research panels imitating the physical and chemical properties of human hair are fabricated and used as measuring objects. By comparison between the sensor output and human sensory evaluation of the panels, it is confirmed that this sensor system is available for monitoring hair by both dry and wet condition.
