Title:
PIEZOELECTRIC MATERIAL, METHOD FOR MANUFACTURING THE SAME, PIEZOELECTRIC COMPOSITION, ULTRASONIC TRANSDUCER, AND ULTRASONIC IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2016219662
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a piezoelectric material having a superior piezoelectric property, a piezoelectric composition including such a piezoelectric material, an ultrasonic transducer, and an ultrasonic imaging device.SOLUTION: An ultrasonic transducer 100 comprises: a backing layer 110; a flexible printed board 120; a piezoelectric composition 130; channels 140 and 141; a filler 150; an acoustic matching layer 160; an acoustic lens 170; and an adhesive layer 180. The piezoelectric composition 130 consists of a piezoelectric material expressed by the general formula DTX. In the general formula, D represents Eu or Yb, T represents Cr or Cu, X represents Ga or Sn. The ultrasonic transducer 100 is mounted on an ultrasonic imaging device.SELECTED DRAWING: Figure 3
