要約(英語): In this paper, we fabricated periodic Si micro-bump structure, and sensory evaluation of tactile feeling of roughness and frictional resistance with human finger was conducted with paired comparison method. In addition, friction coefficient between the micro-bump array and an artificial urethane finger model that mimics human fingertip was evaluated. The samples had various bump sizes with width of 20～600 μm and space of 20 μm. The space between the bumps (20 μm) was decided so that finger skin cannot enter the grooves. The result of sensory evaluation showed that rough feeling was increased with decreasing the micro bump size from 600 μm to 50 μm due to the edge effects of micro bump. The friction resistance feeling was influenced by contact area between the skin and bump surface. In addition, the friction resistance feeling was strong when the micro bump size was 50 μm. Also, the stick-slip phenomenon was strongly observed in the frictional measurement using artificial finger model.
