14. A sealing device, comprising:
-
at least one electroactive polymer element; a core; a first electrode; and a second electrode, wherein the at least one electroactive polymer element forms a flange shape, wherein the flange shape moves toward the core when voltage is applied between the first and second electrodes.

15. A sealing device, comprising:
-
a moment arm; an electroactive polymer element; a first electrode; a second electrode; and a core, wherein a first end of the electroactive polymer element is operatively attached to the core and a second end of the electroactive polymer element is operatively attached to the moment arm, wherein the moment arm is operatively attached at a position along the core so that the moment arm can rotated about the position wherein the first electrode is operatively connected to a first side of the electroactive polymer element and the second electrode is operatively attached to a second side of the electroactive polymer element so that when a voltage difference is applied between the first and second electrodes the moment arm is rotated about the position.
