1. A peristaltic pump assembly for moving a working fluid comprising:

  • an expandable fluid that changes in volume due to the presence of at least one of a magnetic field and an electric field;

    a flexible member interposed between the working fluid and the expandable fluid; and

    a field generator operable to cause the expandable fluid to change in volume by applying at least one of a magnetic field and an electric field to the expandable fluid, which, in turn, moves the flexible member to increase the pressure of the working fluid to thereby move the working fluid.
