30. A telescoping actuator assembly, comprising:
-
a plurality of cylindrical actuators in a concentric arrangement and defining a common longitudinal axis, each of said cylindrical actuators being at least one piezoelectric fiber composite actuator having a plurality of piezoelectric fibers extending parallel to one another and to said common longitudinal axis, each of said cylindrical actuators coupled to concentrically-adjacent ones of said cylindrical actuators such that said plurality of cylindrical actuators can experience telescopic movement along said common longitudinal axis; and an electrical energy source coupled to said plurality of cylindrical actuators for applying actuation energy thereto to generate said telescopic movement. - View Dependent Claims (31, 32, 33, 34)
