Abstract
Actuation systems and devices using an electrically deformable material are disclosed. In the embodiments, a bidirectional actuator assembly includes a first unit including an electrically deformable material coupleable to an activation voltage and configured to provide a displacement in a first direction when the activation voltage is applied to the first unit. A second unit is serially electrically coupled to the first unit and includes an electrically deformable material coupleable to the activation voltage and configured to provide a displacement in a second direction that is different from the first direction when the activation voltage is applied to the second unit. A unidirectional actuator assembly includes at least one unit including an electrically deformable material coupleable to an activation voltage, wherein the electrically deformable material provides a displacement in a selected direction when the activation voltage is applied to the at least one unit.
