Investigation of the role of contact-induced vibrations in tactile discrimination of textures

Abstract: Tactile perception of texture is meaningful for numerous industrial and social applications. While the sense of touch is provided by several contributing factors, each related to different sensory cutaneous units, textures with non-low spatial gradients can be appreciated only by the relative motion between the finger and the object. This work focuses on investigating the role that the vibrations induced during sliding contact play in the origin of tactile perception and surface texture discrimination. We shal… Show more

“…During object manipulation and surface exploration tasks, the sliding contact between the fingertips and the touched surfaces generates vibrations, which propagate through the skin and activate the mechanoreceptors. The amplitude and the frequency of such contact-induced vibrations convey information on the topographical features of the touched surface, thus determining tactile perception [79][80][81][82][83][84]. The ability of the sensor to respond differently to a wide range of frequencies is very useful for various applications such as tactile sensor and nanogenerator, allowing detection and exploitation of vibrations from several natural resources.…”

“…The correct modeling of contact interfaces is a key factor in many engineering applications that inherently include contacts between components, e.g., friction joints [1][2][3], clamping devices, robotic contacts, rolling bearings [4,5], brake systems [6], etc. Contact mechanics between component surfaces also play a key role for understanding many tribological processes, such as friction-induced vibrations [7][8][9][10][11], stick-slip phenomena [12][13][14], frictional instability [7,15], adhesion, and wear [16,17]. An accurate contact modeling of such systems requires knowledge of interface contact parameters [18] such as contact stiffness, which are not easily measurable and completely understood.…”

“…Texture tactile perception refers to tactile experiences and feeling which is gained by touching subtle profile changes of real object surface through the force tactile sensing channel of human [1,2,3]. The texture tactile reproduction is to simulate and replicate the tactile touching when human skin interacts with the objects through some technological means, so that operator can perceive tactile information of the objects in the virtual world [4,5,6].…”
