Outline of Final Research Achievements

In this study, as the basic research of the structure fixing method to the growing living tissue, we fabricated micro suction cup arrays with an adjusting structure of the contact area. We measured the peel-off forces in compressing and shear directions. As the result, the peel-off force changes according to the size of the adjusting structure. Moreover, we observed the peel-off forces in both compressing and shear direction when the micro suction cup arrays attached to the gelatin, which is usually used as a model of living tissue.
