| Outline of Final Research Achievements |
It is well known living organisms have functional surfaces, which are adapted for their living environments. Recent years, biomimetics attract much attention because of their possibility for creating novel functional materials. In this research, we focused on firebrat because firebrat lives in narrow spaces and their surfaces are frequently contacted to environmental surfaces. So, we speculate their body surface would be adapted to reduce friction and wear. As results of surface analysis of a firebrat, firebrats were completely covered by scales, which surfaces have periodic microgroove structures. And groove periods are almost uniform within each scale. However, groove periods around only the head vary between scales. Friction force measurements revealed that firebrat scale reduces friction by decreasing contact area. Further, the heterogeneous groove periods of the scales suggest that it is difficult to fix the whole body in particular rough surfaces and that lead to "fail-safe".
