Abstract: A piezoelectric actuator includes a first electrode layer, a piezoelectric layer and a second electrode layer. The first electrode layer is formed on a vibration plate. The piezoelectric layer is formed on the first electrode layer, the piezoelectric layer comprising piezoelectric particles formed on the surface of a self-assembled monolayer. The second electrode layer is formed on the piezoelectric layer to face the first electrode layer. Thus, a self-assembled monolayer is formed, so that the piezoelectric characteristics of a piezoelectric layer and/or the stiffness of the piezoelectric layer may be increased. Thus, piezoelectric characteristics of the piezoelectric actuator may be enhanced, and the required voltage, which is required to realize a proper deformation amount of the piezoelectric actuator, may be decreased. Moreover, the stiffness of the piezoelectric actuator may be increased, so that the vibration remaining at the piezoelectric actuator may be minimized even though the driving is finished.

Abstract translation: 压电致动器包括第一电极层，压电层和第二电极层。 第一电极层形成在振动板上。 压电层形成在第一电极层上，压电层包括形成在自组装单层表面上的压电颗粒。 第二电极层形成在压电层上以面向第一电极层。 因此，形成自组装单层，从而可以增加压电层的压电特性和/或压电层的刚度。 因此，可以增强压电致动器的压电特性，并且可以减小实现压电致动器的适当变形量所需的所需电压。 此外，可以增加压电致动器的刚度，使得即使完成驱动，压电致动器处残留的振动也可以最小化。
