PIEZOELECTRIC LAYER OF ULTRASOUND TRANSDUCER, ULTRASOUND TRANSDUCER, AND METHOD OF MANUFACTURING PIEZOELECTRIC LAYER OF ULTRASOUND TRANSDUCER

摘要

Disclosed are a piezoelectric layer of an ultrasonic transducer, an ultrasonic transducer, and a method of manufacturing the piezoelectric layer of an ultrasonic transducer. A piezoelectric layer according to an embodiment includes a piezoelectric element; polymer bridges formed on both sides of the piezoelectric element; and a plating film formed on the piezoelectric element and the polymer bridge, wherein a polarization for separating the plating film into a signal line and a ground line is formed in a part of the polymer bridge on which the plating film is formed.
