MICROSTRUCTURE ARRANGEMENT FOR GRIPPING LOW COEFFICIENT OF FRICTION MATERIALS

A microstructure arrangement having a substrate; a first set of pillars having a cross section area in the range of 10 μm2 to 400 μm2 and a pitch in the range of 20 μm to 1000 μm; a second set of pillars disposed on said first set of pillars having a cross section area less than that of the pillars...

More Information
Summary:A microstructure arrangement having a substrate; a first set of pillars having a cross section area in the range of 10 μm2 to 400 μm2 and a pitch in the range of 20 μm to 1000 μm; a second set of pillars disposed on said first set of pillars having a cross section area less than that of the pillars in said first set of pillars; wherein said second set of pillars are defined by pillars each having a cross section width from 0.5 μm to 100 μm and a pitch in the range of 1 μm to 200 μm; and, wherein said first and second set of pillars are configured to cooperate to have a 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.
