Stooped Nanohairs: Geometry‐Controllable, Unidirectional, Reversible, and Robust Gecko‐like Dry Adhesive

A simple yet robust method to fabricate an array of stooped nanohairs is presented, with a proper choice of material and post e‐beam exposure even for an aspect ratio of 10. The stooped nanohairs have the unidirectional feature of frictional adhesion with a remarkably high adhesion force (∼11 N cm−2...

Summary:A simple yet robust method to fabricate an array of stooped nanohairs is presented, with a proper choice of material and post e‐beam exposure even for an aspect ratio of 10. The stooped nanohairs have the unidirectional feature of frictional adhesion with a remarkably high adhesion force (∼11 N cm−2).
