Abstract:
1. An apparatus including a plurality of ultrasound transducers, each ultrasound transducer comprising: a first electrode; a second electrode, the first electrode and the second electrode having an electrode separation; a thin film located between the first electrode and the second electrode, the thin film comprising a piezoelectric material having a film thickness; and a substrate supporting the plurality of ultrasound transducers, the electrode separation being less than 10 microns, each transducer comprising a multilayer structure including the first electrode, the thin film, and the second electrode, the first electrode, thin film, and second electrode being generally parallel, the multilayer structure being generally planar and disposed parallel to the substrate, each ultrasonic transducer having an elongated form having a length and a width, the length being at least double the width, the multilayer structure being partially released from the substrate and supported on the substrate so as to form a T-bar shaped transducer.
