| Research Abstract |
We have focused friction phenomena on human skin surfaces to show arousal mechanisms of tactile senses and emotions by external stimuli when humans touch objects by their fingertips. We found that stick-slip feel which is caused by a characteristic frictional stimulus with large acceleration is one of the cues to differentiate water from other liquids. This stimulus could activate tactile receptors: Meissner's corpuscle and Pacinians. In addition, we have shown the physical origins of tactile textures for biological materials, cosmetic sponges and soaps. These findings could potentially be applied in the following areas: fabrics, cosmetics, automobiles, robotics, and information devices.
