  • Magnetostrictive torque sensor
    Patent number: 5315881
    Abstract: Magnetostrictive wire having a low surface-to-volume ratio established by a onstant non-planar cross-section, is helically deformed into contact with a shaft under a stress maintaining the wire in fixed relation to the shaft surface. Magnetic anisotropy is imparted to the wire by twist thereof about its cross-sectional axis while the wire is being helically deformed into contact with the shaft surface to form a torque sensor through which accurate torque detection is achieved.
    Type: Grant
    Filed: October 23, 1992
    Date of Patent: May 31, 1994
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Howard T. Savage, Arthur E. Clark, Marilyn Wun-Fogle, Lawrence T. Kabacoff, Antonio Hernando, Bruce Beihoff
