1. A device for measuring the movement of an object comprising:

  • a. means for creating time-varying magnetic fields at least large enough to surround the object;

    b. electrical circuits adapted to conform to the surface of the object;

    c. noise reduction circuit means for reducing the sum of signals from an unwanted magnetic field of uniform intensity that is influencing the fields created to surround the object to zero; and

    d. voltage monitoring means connected to the electrical circuits, whereby motion of the surface creates a measurable change in induced voltage in the circuits that correlates to the movement of the object.
