1. A method for sensing pressure within a work object comprising:

  • A. placing an electrically deformable member on the work object so as to cover a portion of the surface area thereof;

    B. applying electrical energy to said member to cause the member to deform thereby applying pressure to said portion of the surface area of the work object; and

    C. sensing the tension in said member dependent upon the amount of resistance to deformation imparted by the pressure within said work object.
