Purpose

  • Among several tactile sensors in use currently, none can evaluate the sense of gentle touch. We have developed a fibratus tactile sensor that utilizes the property of reflection. This sensor enables to evaluate the sense of gentle touch. We propose a new interface device that employs this fibratus tactile sensor.
    If we can evaluate touch sensation information with respect to fibratus salience, the acquired information can be very useful for interactive devices. We can then implant fibratus salience into the flexible mirror surface. From this salience, the end of the fibratus is considered to be the contact surface and the reflection characteristics are left. This salience indicates that the sensor functions as a fibratus tactile sensor.

Method

  • We have proposed a new optical tactile sensor that can detect the surface deformation with high precision by using the principle of an optical lever. Transparent silicone rubber is used as the flexible mirror surface RefShape.
    We implant fibratus salience, the hardness of which is a little greater than that of silicone rubber, into the flexible mirror surface. From this salience, the end of the fibratus is considered to be the contact surface and the reflection characteristics remain unchanged. This salience indicates that the sensor functions as a fibratus tactile sensor.
