Abstract
(EN)
Provided is an organic piezoelectric material for constructing an ultrasonic vibrator that has good durability in a manufacturing process and a usage environment, is superior in piezoelectric characteristics, and is suited for high-frequency and wideband. Also provided are a manufacturing method for the same; ultrasonic vibrator using the same; ultrasonic probe; and ultrasonic medical image diagnostic device. The organic piezoelectric material is a material in which electrodes are installed on both surfaces of the material and characterized in that after the electrodes have been installed, pressing by the insulating member and polarization processing have been applied.

L'invention porte sur un matériau piézoélectrique organique destiné à construire un vibreur à ultrasons qui possède une bonne durabilité dans un processus de fabrication et un environnement d'utilisation, possède d'excellentes caractéristiques piézoélectriques, et est approprié pour un fonctionnement à fréquence élevée et à large bande. L'invention porte également sur un procédé de fabrication de ce matériau ; un vibreur à ultrasons l'utilisant ; une sonde ultrasonore ; et un dispositif de diagnostic par imagerie médicale ultrasonore. Le matériau piézoélectrique organique est un matériau dans lequel des électrodes sont installées sur les deux surfaces du matériau et est caractérisé en ce qu'après que les électrodes ont été installées, une pression par l'élément isolant et un traitement de polarisation ont été appliqués.
