Image analysis for deformation behavior of optical based silicone tactile sensor

This paper presents a tactile sensor which is made of a silicone based material. The tactile sensor is designed similarly like a human finger. The hollow space inside the tactile sensor is marked at the `finger tip' inner side to sense any deformation when force is apply outside the `finger tip'. The force is apply by using micrometer tip. A CCD camera is connected to a fiberscope and the fiberscope is connected to the tactile sensor to `see' the deformed image inside the silicone dome. Several images is captured. The captured image is analyzed by a WiT image processing algorithm. Based on the processed images, the result is analyzed and the deformation behavior is studied.
