Mechanically Switchable Elastomeric Microfibrillar Adhesive Surfaces for Transfer Printing

Authors


Abstract

image

A new mechanically switchable topographical adhesive surface for transfer printing is reported. The surface consists of a thin non-adhesive mesh and pillars, coated with a dry microfibrillar adhesive, extending through the holes in the mesh. The switching is achieved by retracting the pillars. 2000-to-1 switching ratios and examples of part transfer applications are shown.
