About the Cover:

In article number 202202978, Tae-Heon Yang, Changhyun Pang and co-workers report that a highly adaptive soft microstructured switchable adhesion device, which is inspired by the geometric and material characteristics of the tiny denticles on the surface of an octopus sucker. Owing to the presence of artificial microdenticles, the adhesive device demonstrates effective transport on soft, curved objects with high roughness in dry and wet conditions.
