Abstract
A magnetostrictive actuator, comprising: a magnetostrictive member which elongates upon application of a magnetic field; a translating member mechanically coupled to the magnetostrictive member, for translating the change in length of the magnetostrictive member into a desired action; and a selectively-energized coil surrounding the magnetostrictive member, to apply a magnetic field to the magnetostrictive member, and thus selectively change the length of the magnetostrictive member, and thereby cause the translating member to create the desired action.
