Abstract
A dry adhesive structure and a method for manufacturing thereof is disclosed. In an embodiment, the dry adhesive structure comprises a base structure and a plurality of fiber structures is disclosed, wherein each of the plurality of fiber structures comprises a cap structure that substantially overhangs its corresponding fiber structure on at least one side. The method for manufacturing the dry adhesive structure comprises applying a photosensitive material to substrate comprising polymethyl acrylate, patterning and developing the photoresistive material to form a mask comprising the overhanging cap structure, exposing the mask to UV light, developing the substrate to form undercut fiber structures, molding an elastomer rubber materials to form an elastomer rubber negative mold, and molding a flexible polymer material in the elastomer rubber negative mold to form the dry adhesive structure.
