| Research Abstract |
The objective of this study is to establish the method for microscopic design the tactile sense-oriented materials, and we examined the relation between tactile sensation and microscopic physical behavior of the object materials. In the skin care formulations, the wettability, which was quantitatively measured by the contact angle, of the human skin highly effects on the tactile sense. The rheological property of the sample is also affected by the wettability of the human skin by the samples. In addition, we investigated the difference between two tactile senses that has statistically similar inner structure but induce much different sensations, comfort and discomfort, such as tactile feelings of "moistness" and "sticky". The sensory score of "moistness" strongly related to the contact angle of the sample, whereas that of "sticky" related to the adherability, showing the two sensations are induced by different interfacial physical interactions.
