Summary:A microstructure arrangement for gripping low coefficient material comprising: a substrate disposed on a gripping surface; a set of pillars disposed on the substrate; and, wherein the set of pillars have the physical property of a grip force in excess of 50.0N with a contact area of 25% or less as determined by the friction testing method. A first set of pillars can be disposed on the substrate having a cross section area in the range of 100 μm2 to 160,000 μm2, height relative to the substrate in the range of 10 μm to 400 μm, and a pitch determined from the center of the pillars, in the range of 20 μm to 1000 μm; and a secondary set of pillars disposed on the first set of pillars having a cross section area less than that of the pillars in the first set of pillars.
