A piezoelectric device comprises a thin layer 12 of piezoelectric ceramic material mounted upon a substrate 10, wherein: the layer of piezoelectric ceramic material is a composition of a "piezoelectric" ceramic in powder form distributed within a continuous phase of a glass-like binding agent, and is formed and thereafter electrically polarised in situ. The layer of piezoelectric ceramic may be of laminated construction.The piezoelectric material may consist of a lead zirconate/titanate compound in a lead borosilicate binder. A liquid carrier is further included so as to produce a paste suitable for screen printing. <IMAGE> |
