Abstract:
1. A device for directional and distributed control of adhesive forces, comprising: (a) a plurality of parallel anisotropic hair features making an acute angle with respect to a reference plane to define a hair direction, wherein each of said plurality of parallel anisotropic hair features further comprises a tip angle with respect to said reference plane and with the hair tip tapered asymmetrically and in the direction of said hair direction; (b) a backing layer with embedded therein a flexible and inextensible fiber, said backing layer affixed to said plurality of parallel anisotropic hair features; and (c) a plurality of segments affixed to said backing layer on the side of said backing layer opposite to said plurality of anisotropic hair features, wherein the segment thickness increases height in a direction opposite to said hair direction, and wherein said backing layer hinges at gaps between said plurality of segments.
