Patent ID: 11453347

Abstract:
A suction device including a casing having a central post extending through the casing. A flexible member is provided across a free end of the central post. One or more artificial muscles are housed within the casing and encircle the central post, each artificial muscle including a housing having a first wall and a second wall opposite the first wall. The housing having an electrode region adjacent an expandable fluid region, a dielectric fluid housed within the housing, and an electrode pair housed within the electrode region of the housing. The electrode pair includes a first electrode coupled to the first wall and a second electrode coupled to the second wall. The electrode pair is actuatable between a non-actuated state and an actuated state such that actuation from the non-actuated state to the actuated state directs the dielectric fluid into the expandable fluid region and deforms the flexible member to form a suction area at the free end of the central post.
