Outline of Final Research Achievements

In this study, influence of the structure inclination of a reversible adhesion type gecko inspired device incorporating the characteristics of micro/nano-structures of gecko foot hairs was clarified from both theoretical and experimental point of view. In addition, possibility of manipulation using the developed adhesive device was discussed. Specifically, manufacturing process of micro inclined structure on the surface of the devices was first investigated. By the proposed method, adhesive devices with various tip shapes were produced. From the adhesive force measurements using these devices, the effect of inclination of the structure on the adhesion force variation, and the effect of tip shape on the absorption of the surface roughness were investigated. Additionally, object manipulation using the produced adhesive device was succeeded based on these results.
