Abstract

1,097,013. Piezoelectric transducers. PLESSEY-U.K. Ltd. March 17, 1965 [March 26, 1964], No. 12970/64. Heading H1E. In the manufacture of a bimorph element having thin strips of a permanently polarizable material having piezoelectric or electroatrictive properties carried on opposite faces of a thin metallic support member, the strips are polarized before being fixed to the support member. A sheet of lead zirconate titanate ceramic material is coated on each face with silver and baked, and polarized by applying a voltage between electrodes secured to the two silver layers while the sheet is immersed in liquid paraffin at 140‹ C. The sheet is cleaned and cut into strips, and silver conductive cement applied to the positive face of one strip and the negative face of another, whereafter a shim of brass is sandwiched between the two cemented faces and the composite assembly is cured by heating under pressure. Alternatively, two sheets of polarized material may be cemented to the opposite faces of a brass sheet and cured prior to cutting the composite assembly into separate bimorph elements.
