Abstract
A piezoelectric transducer formed of a body of piezoelectric material having first and second opposed sides and first and second electrically conductive layers on the first and second sides respectively of the piezoelectric body, wherein the piezoelectric body and the electrically conductive layers are so constructed that they form a plurality of separate adjacent series-connected transducer elements. A method of manufacturing such a transducer is also disclosed. The piezoelectric body may have a substantially uniform direction of polarization, or alternating zones of opposite polarization. The conductive layers may be continuous or discontinuous, together forming isolated electrode pairs to define the individual transducer elements. The elements can be hard wired or connected through a switching circuit to display either circumferential or axial or other ultrasonic focal patterns, and may be connected in a parallel, rather than a series configuration. When connected in series, advantageously higher impedance can be obtained, compared to the parallel configuration.
