| Outline of Final Research Achievements |
Skin is important for tactile sensation since the skin works for mechanoreceptors as mechanical signal processing. This study has focused on collagen fibers within subcutaneous tissue, which has been often analyzed by using a uniform model, and proposed a new skin model including collagen fibers. The aim of this study is a development of a 3-D skin model capable of simulating the transmission of mechanical stimuli given the skin to mechanoreceptors. First, the proposed model was verified by using 2-D model compared to previous studies, and dynamic analysis using the proposed model showed that collagen fibers contribute high sensitivity and broad receptive field for tactile sense. Then, consecutive transverse cross-sectional samples of a postmortem Macaca fuscata’s finger were created and 3-D texture of collagen fibers was observed under a microscope.
