Abstract:
A multilayer electrostrictive element comprising:a stack formed by a plurality of electrostrictive substrates piled upon one another, said stack having a peripheral surface defining a cross-sectional area of said stack;a plurality of interior electrodes disposed between said electrostrictive substrates, each of said internal electrodes having peripheral ends on said peripheral surface and each of said internal electrodes having an internal electrode area which is substantially equal to a cross-sectional area of said stack;a first external electrode having a first plate like body and a plurality of first projections integral with the first plate like body, said plurality of first projections are protruded at a pitch corresponding to said internal electrode on alternate layers and connected to said internal electrodes on alternate layers; anda second external electrode having a second plate like body and a plurality of second projections integral with the second plate like body, said plurality of second projections are protruded at a pitch corresponding to said internal electrode on alternate layers and connected to said internal electrodes on alternate layers.
