ABSTRACT:
An actuator (1) having at least one triggerable element (4,5) of variable lengths made of a multifunctional material (6) for large regulating distances is disclosed. The multifunctional material is arranged in layers on a deformable platform carrier structure 93), the carrier structure and the multifunctional material being disposed symmetrically about a longitudinal center plane (7) of the actuator. The carrier structure includes at least a pair of arcuate sections formed on both sides of the longitudinal center plane of the actuator, each such arcuate section describing an arc of at least 180.degree.. The triggerable elements of variable lengths may be actuated with heat supplied by a separate heat source, or by electricity provided from a separate source of electricity so that the triggerable elements either expand or contract, thus moving a stringer (26) formed as a part of the carrier for performing the desired actuation function.
