ULTRASONIC TRANSDUCER, AND ULTRASOUND DEVICE INCLUDING SAME AND METHOD OF MANUFACTURING SAME

摘要

The ultrasonic transducer comprises: a piezoelectric body for converting electrical energy to mechanical vibrations and generating ultrasonic waves; an upper electrode formed on the upper portion of the piezoelectric body, transfers the electrical energy to the piezoelectric body, and includes divided patterns; a conforming layer formed on the top of the upper electrode and formed of divided patterns that are the same as the divided patterns of the upper electrode; and a multifocal lens formed on the conforming layer and having at least two or more curvatures in order to form multiple focal points. Accordingly, the beam shape in the width direction can be improved in order to provide a high performance ultrasonic transducer.
