Abstract: Fabrication techniques for gecko-inspired adhesives generally target mold durability, adhesive performance, and process efficiency and simplicity. With these goals in mind, we present a micromachining process for creating ...

Abstract: We report a surface treatment for an elastomeric dry adhesive that improves adhesion, especially on surfaces with microscopic roughness. The process involves coating wedge-shaped polydimethylsiloxane (PDMS) features of the ...

Abstract: We describe a process for creating durable metal molds for the fabrication of directional, gecko-inspired dry adhesives. The adhesives require microscopic inclined features with a challenging combination of tapered geometry, ...

Abstract: Biological systems such as the gecko are complex, involving a wide variety of materials and length scales. Bioinspired robotic systems seek to emulate this complexity, leading to manufacturing challenges. A new design for ...
