An apparatus for controlling a phase transition temperature of a shape memory alloy

摘要

A device for controlling a phase transition temperature of a first shape memory alloy is adapted to, the apparatus comprising:a primary wire, which consists of the first shape memory alloy is;the primary wire a first and second end, wherein the first end is rigidly fastened to a structure and the second end to the adjustment in the position is;a activation source, the thermally coupled with the wire and is operable to selectively a reversible conversion of the primary wire of a martensite-phase to an austenite phase to effect during a cycle;a load element, which functionally connected with the primary wire and is configured in such a way, a tensile load on the primary wire to selectively when an increase in the ambient temperature at or above a threshold temperature, as a result of which the phase transition temperature of the primary wire is increased.
