A switchable gecko-inspired adhesive that shows anisotropic adhesion and friction properties is presented. With proper actuation, the polymer-based dry adhesive provides strong adhesion and friction forces for attachment (or gripping), or weak forces for detachment (or releasing). The reusability of the dry adhesive is also demonstrated over multiple attachment/detachment cycles.
