Thumbnail image of graphical abstract

A reversible mechanical interlocker inspired from the wing locking device of beetles is reported on page 475, by Kahp-Yang Suh and co-workers. The interlocker is highly flexible and displays an extremely high shear locking force of ∼40 N/cm2 as well as an easy normal lift-off. The image shows an illustration for the wing-locking device of beetles that is operated by interconnecting densely-populated microhairs (termed microtrichia) on the cuticular surface.
