1. A method comprising:
depositing a curable material onto a primary electrode;
curing the deposited curable material to form an electroactive polymer element comprising a cured elastomer material; and
depositing an electrically conductive material onto a surface of the electroactive polymer element opposite the primary electrode to form a secondary electrode;
wherein the cured elastomer material has a Poisson's ratio of between approximately 0.1 and approximately 0.35.
