发明名称 COMPOSITE ULTRASONIC TRANSDUCER ARRAY OPERATING IN THE K31 MODE
摘要 An ultrasonic transducer array element operating in the k31 mode is formed by two piezoelectric subelements (A1, A2; B1, B2; C1, C2) joined to form a 2-2 composite by a conductive filler material (72, 76, 79). An energizing potential is applied to the conductive filler material, and a return potential is applied to the outer opposing faces of the subelements. Preferably the conductive filler material comprises a conductive epoxy. Arrays of such elements in one and two dimensions are formed with the conductive epoxy in alternating kerfs in a row being connected to the opposing polarities of an energizing potential.
