Abstract:
A piezoelectric transducer, comprising:a first solid state body of a single unitary piece of piezoelectric material having a longest dimension defining a lengthwise direction;a plurality of stripe-shaped actuating electrodes that are each arranged on outer surfaces of said solid state body so as to extend at least substantially entirely around a perimeter of said solid state body defined by said outer surfaces, and that are respectively spaced apart from one another in said lengthwise direction;a support plate; andfirst and second contact electrodes that each respectively comprise a spine electrode and contact fingers extending therefrom, arranged on a first surface of said support plate such that said contact fingers of said first contact electrode are alternately interdigitally intermeshed with said contact fingers of said second contact electrode;wherein said solid state body is arranged on said support plate with alternating ones of said actuating electrodes electrically contacting respective ones of said contact fingers of said first contact electrode and of said second contact electrode alternately.
