ABSTRACT:
A shape memory element (a structure formed from a shape memory alloy) includes an electrically conductive ferromagnetic material. The ferromagnetic material may be magnetostrictive. In some embodiments, the shape memory element is formed from a shape memory alloy core and has a cladding over the core that includes the ferromagnetic material. In other embodiments, the shape memory alloy may be selected to be ferromagnetic.
