摘要： An ultrasonic transducer comprises a stack having a first face 102, an opposed second face 104 and a longitudinal axis Ls extending therebetween. The stack comprises a plurality of layers, each layer having a top surface and an opposed bottom surface, wherein the plurality of layers of the stack comprises an upper unpoled piezoelectric layer 126, an underlying lower poled piezoelectric layer 106, and a dielectric layer 108. The dielectric layer 108 is connected to the piezoelectric layer 106 and defines an opening extending a second predetermined length in a direction substantially parallel to the axis of the stack. A plurality of first kerf slots 118 are defined therein the stack, each first kerf slot extending a predetermined depth therein the stack through the upper piezoelectric layer 126 and into the lower piezoelectric layer 106 and a first predetermined length in a direction substantially parallel to the axis.

摘要： A membrane hydrophone for analyzing high frequency ultrasound transducers has a piezoelectric membrane with electrode patterns created on the surface of the membrane. In one embodiment, the electrode patterns are doubled on each side of the membrane except for an active area of the hydrophone. In one embodiment, the electrodes are formed by removing a conductive coating on the membrane with laser pulses. The laser is set to remove the conductive coating from the piezoelectric membrane from the same side of the membrane in order to accurately align the electrodes in the active area. In one embodiment, the active area of the hydrophone has an area in a range of 900 - 10,000 square microns.
