RISCompression Molding and Nickel Molds for Directional Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the fabrication of directional gecko-inspired adhesives, a new capability made possible by the availability of metal molds is hot compression molding. This molding process allows the use of elastomers with much higher ...
PEDOT:PSS Coating Improves Gecko-Inspired Adhesive Performance
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
A Passive Parallel Master–Slave Mechanism for Magnetic Resonance Imaging Guided Interventions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A passive, parallel master–slave mechanism is presented for magnetic resonance imaging (MRI)guided interventions in the pelvis. The mechanism allows a physician to stand outside the MRI scanner while manipulating a needle ...
The Role of Tissue Slip Feedback in Robot-Assisted Surgery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Slip, or accidental loss, of grasped biological tissue can have negative consequences in all types of surgery (open, laparoscopic, robot-assisted). This work focuses on slip in robot-assisted surgery (RAS) with the goal ...

Creating Metal Molds for Directional Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
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, ...
Simulation-Guided, Application-Specific Manufacturing of Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We introduce a simulation-based approach to specify tool trajectories for micromachining the molds that are used to create directional gecko-inspired adhesives. A challenge is that the final feature geometries are different ...
Surface and Shape Deposition Manufacturing for the Fabrication of a Curved Surface Gripper
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Microwedge Machining for the Manufacture of Directional Dry Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Directional dry adhesives are inspired by animals such as geckos and are a particularly useful technology for climbing applications. Previously, they have generally been manufactured using photolithographic processes. This ...
Cutting to the Point: Directly Machined Metal Molds for Directional Gecko-Inspired Adhesives
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
