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 ).
