Abstract
An SMA wire actuating element is described, having a shape memory alloy wire intended to be operably connected to an actuatable element of an actuator device, and a first and a second elongated elements made of a non-SMA material. The elongated elements are respectively restrained at a first end thereof to the ends of the shape memory alloy wire by way of crimping means of the SMA wire actuating element. The SMA wire actuating element further has a first and a second connection means intended to be operably connected to a body of the actuator device. The elongated elements are respectively restrained at a second end thereof to the connection means, whereby the portion of each elongated element comprised between its first and second ends is free to move between the crimping means and the connection means.
