Abstract
This invention is directed to an improved contact surface for manipulating articles wherein the microstructure included on the contact surface having a plurality of pillars spaced apart in the range of 200 μm and 600 μm, having a height in the range of 50 μm and 1200 μm, a width of in the range of 70 μm and 300 μm, a wall draft angle between 0° and 15°, a density of in the range of 5,000 to 20,000 pillars per square inch, and a friction rating greater than 7. The contact surface can be included on a sewing machine feed dog, a glove, sporting equipment, firearm grip, hand rail, tool grip, tool handle, and a strap such as for a satchel or backpack.
