Abstract: Since the excitement of gecko free-walk on a smooth surface is
discovered with the cause of Wan der Waals force, researchers have focused on
the development of biomimetic gecko tape. Hierarchical structure and
anisotropic adhesion are two of the spotlights. However, little work has been
done on integration of these two parameters. This paper presents a model design
of orientated micro-and nano-arrays including three levels of setae, branches
and spatulae. Finite element method is applied for compression shear test
simulation. The anisotropic property is controllable due to the hierarchical
surface design.
