Title
(EN) STRUCTURED ACTUATORS: SHAPED ELECTROACTIVE POLYMERS
(FR) ACTIONNEURS STRUCTURÉS : POLYMÈRES ÉLECTROACTIFS STRUCTURÉS
Abstract
(EN)
An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.
(FR)
L'invention concerne un ensemble actionneur comprenant une électrode primaire, une électrode secondaire chevauchant au moins une partie de l'électrode primaire, et une couche de polymère électroactif disposée entre l'électrode primaire et l'électrode secondaire, la couche de polymère électroactif comprenant une paroi latérale non verticale (par exemple, inclinée) par rapport à une surface principale d'au moins l'une des électrodes. La couche de polymère électroactif peut être caractérisée par une forme non axisymétrique par rapport à un axe qui est orienté orthogonalement à une surface principale d'électrode.
