Abstract
This paper is a study on the development of a sensor for measuring tactile sensation. The sensor using pyroelectric of a PVDF (Polyvinylidene Fluoride) film is assembled. The base of the sensor is an aluminum, around which a synthetic rubber layer overlaid with Nichrome wire, a PVDF film and a protective layer of acetate film are stacked in sequence. The sensor is heated and kept at a constant temperature by Nichrome wire and thermistor attached on the sensor through PID control. The heated sensor is contacted with the object to obtain output of pyroelectric effect from the PVDF film. Through experiments on different fabrics, the results show that the PVDF sensor using pyroelectric is 'available to obtain information on warm feeling.
