材料･商品開発のための触覚センシング

抄録

The perception of tactile sensation in human touch is significant as it serves as a vital source of information for evoking various emotions and for comprehending the physical characteristics of materials and assessing theeffectiveness of products. We employed a biomimetic tactile sensing system, which mimics the physiological process of generating tactile sensation through a finger model and sinusoidal motion, to evaluate the tactile textures of various objects. By focusing on interfacial phenomena, particularly friction, that occur on the skin’ s surface, we were able to determine the physical mechanisms of textures such as“ moistness,”“ smoothness,” and“ warmth.” These methods were also applied to the evaluation of various materials and products, including cosmetics and paints. The results of these evaluations will be utilized to develop more realistic virtual reality systems and tactile humanoid robots, as well as textiles, cosmetics, and automotive materials.
