Influence of substrate roughness on lifting performance. A) From top to bottom, the roughness is increased. During lifting, air leakage occurs more strongly for high substrate roughness, resulting in higher vacuum pressure inside the deformed chamber, thus requiring larger deformation to reach the same lifting force. From left to right: Topographical 3D images of the 3 PMMA substrates, used in the tests, extracted from the confocal microscope. Pictures of the EA suction cups at 8N of lifting force with three different vacuum chamber volumes (rindicates the radius of the detached area). Schematic cross-section of the EA suction cup showing air leakage path, vacuum pressure, and chamber deformation.
