Abstract:
1. A laterally vibrating stacked micromechanical piezoelectric resonator, comprising: a top electrode; an interleaved electrode; a first piezoelectric layer disposed between the top electrode and the interleaved electrode; a bottom electrode; a second piezoelectric layer disposed between the interleaved electrode and the bottom electrode; said interleaved electrode in contact with said first and said second piezoelectric layers, said first and second piezoelectric layers each having a planar surface having a cantilevered periphery, dimensioned to undergo in-plane lateral displacement at said periphery; and means for applying an alternating electric field across the thickness of at least one of said first and second piezoelectric layers, said electric field configured to cause said at least one piezoelectric layer to have an in-plane lateral displacement that is substantially in the plane of said planar surface.
