    Abstract: An improved strain responsive line sensor detection system which is selectively sensitive to motion of a mass on a surface. In a line sensor having an uniform thin film plated wire, the sensitivity of the line sensor falls off with distance of the intrusion from the source end of the line where are connected the high frequency drive and the processor electronics. In this invention, the thin film plated wire is made monotonically nonuniform along its length in one or more of its magnetic properties and parameters, i.e., the magnetostriction may have a gradient along its length, the plating thickness may have a gradient along its length and be made progressively thicker, and the Hk may have a decreasing gradient along its length, to compensate in whole or in part for the losses in the plated wire thereby making it possible to extend the length of a thin film line sensor.

    Abstract: A magnetostrictive anisotropic thin film plated wire transducer for measurement of deformation of an plastic medium. A length of magnetostrictive plated wire is strung back-and-forth across a transducer framework, the magnetostrictive wire being sensitive to stress and strain. The transducer detects deformation of a surface or a structure generated by external changes in pressure on that surface or structure. The deforming surface either directly induces a stress in the magnetrostrictive plated wire transducer or induces a stress on it via an intermediate medium such as a fluid.
