Abstract
We have developed a wearable tactile sensor using a PVDF film, which detects skin-propagated vibration based on the mechanical interaction between the fingertip and the object. The sensor allows users to touch the object with bare fingertips. The output from this sensor involves in each user's skin mechanical properties as well as touch object and behavior such as contact force and scanning velocity. The sensor has a potential of the evaluation of individual tactile sensations and tactile communications. In this paper, influence of the contact force on the sensor output is investigated. The result shows that the contact force affects the intensity and frequency response of the sensor output.
