1. A parallel kinematic device, comprising:

  • a base plate;

    a mobile plate; and

    at least three kinematic links, wherein each of said kinematic links comprises;

    a first end interconnected to said base plate by a first joint;

    a second end interconnected to said mobile plate by a second joint;

    a slide member;

    a carrier member;

    a first piezoelectric linear actuator assembly, wherein said mobile plate can be moved with respect to said base plate with at least three degrees of freedom, and wherein said first piezoelectric linear actuator assembly comprises;

    a piezoelectric ceramic element comprising;

    a first face;

    a second face; and

    at least a first edge;

    a plurality of electrodes interconnected to said first face;

    a single electrode interconnected to said second face; and

    a finger interconnected to said at least a first edge, wherein selective electrical excitation of at least two of said plurality of electrodes causes said slide member to move relative to said carrier member.
