Anisotropic Adhesion Properties of Triangular-Tip-Shaped Micropillars

Directional dry adhesive microstructures consisting of high‐density triangular‐tip‐shaped micropillars are described. The wide‐tip structures allow for unique directional shear adhesion properties with respect to the peeling direction, along with relatively high normal adhesion.
