Abstract
A piezoelectric sensor comprising an insulator layer having opposing upper and lower surfaces, a first piezoelectric portion having a lower surface in contact with the upper surface of the insulator layer, a second piezoelectric portion having a lower surface in contact with the upper surface of the insulator layer and an insulator strip dividing the first and second piezoelectric portions, wherein the first portion and second piezoelectric portion are laterally positioned with respect to one another in the same generally planar layer.
Claims9
A piezoelectric sensor comprising:
- an insulator layer having opposing upper and lower surfaces;
- a first piezoelectric portion having an upper surface and a lower surface in contact with the upper surface of the insulator layer;
- a second piezoelectric portion having an upper surface and a lower surface in contact with the upper surface of the insulator layer;
- and
- an insulator strip dividing the first and second piezoelectric portions, the insulator strip being a raised portion connected with the insulator layer, the raised portion having an upper surface,
- wherein the first piezoelectric portion, the second piezoelectric portion and the raised portion dividing the first and second piezoelectric portions are laterally positioned with respect to one another, and wherein the upper surface of the first piezoelectric portion, the upper surface of the second piezoelectric portion and the upper surface of the raised portion form the same generally planar upper surface layer of the piezoelectric sensor to maintain a unitary planar sensor profile.
