Abstract
A bioinspired suction device includes a radially symmetrical suction chamber formed from a first elastomer and having a skirt portion with a skirt diameter and a disc margin formed from a flexible flattened ring adhered to a lower surface of the skirt portion. The disc margin is formed from a second elastomer and has a disc diameter that extends beyond the skirt diameter. The second elastomer is a compliant material having a lower hardness and lower tensile strength than the first elastomer. Radial pads may extend from the disc margin, where each pad has elastomeric texture features formed on a pad contact surface.
