Kahp Suh, Hong Lee, and co‐workers present on p. 2276 a simple, yet robust method for fabricating an array of stooped “nanohairs” by applying a proper choice of materials and post e‐beam exposure, even for an aspect ratio of 10. The stooped nanohairs possess the unidirectional feature of frictional adhesion with a remarkably high adhesion force (∼11 N cm −2 ).
