Abstract Scope In small dimensions, objects tend to tenaciously stick to each other. This poses a severe challenge for the handling of micro-components by adhesive polymeric microstructures. Inspired by biological evolution, such surface microstructures have become an innovative and sustainable strategy for robotic gripping and handling. Following successful model experiments, theory and numerical simulation, reliable and robust gripping of objects is now on the path to commercialization. However, as the components to be handled are shrinking in size, their weight will be too small to allow detachment by conventional mechanisms. Our group has proposed various designs that will allow the controlled release and placement of micro-objects. Inspired by a biological example, a metamaterial involving a programmable snap-action was developed. With an unprecedented switching ratio (between high and low adhesion) exceeding 50, such microstructure concepts may enable an energy-efficient solution to handling problems under extreme conditions.
