Claim 16:
17. An artificial muscle comprising:
a housing comprising an electrode region and an expandable fluid region;
an electrode pair positioned in the electrode region of the housing, the electrode pair comprising a first electrode fixed to a first surface of the housing and a second electrode fixed to a second surface of the housing;
a first electrical insulator layer fixed to an inner surface of the first electrode opposite the first surface of the housing, the first electrical insulator layer having a dielectric constant between 10 and 14;
a second electrical insulator layer fixed to an inner surface of the second electrode opposite the second surface of the housing, the second electrical insulator layer having a dielectric constant between 10 and 14; and
a dielectric fluid housed within the housing, the dielectric fluid having a dielectric constant between 1 and 10,
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 the expandable fluid region.
