摘要： An artificial muscle including a housing, an electrode pair positioned in an electrode region of the housing, the electrode pair including a first electrode and a second electrode, the first electrode and the second electrode each including a pair of tapered tab portions and a bridge portion, the tapered tab portions each having a first end proximate to the expandable fluid region and an opposite second end proximate the electrode region, each of the second ends tapering in a direction opposite the expandable fluid region, the pair of tapered tab portions extending parallel to one another to define a gap portion between the pair of tapered tab portions, the bridge portion interconnecting the pair of tapered tab portions, and a dielectric fluid housed within the housing, wherein 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 an expandable fluid region of the housing.
