Abstract
Abstract. The actuators for precise positioning based on bimorph
structures of piezoelectric LiNbO 3 and LiTaO 3 crystals are
considered. The optimal orientations of the actuator plates ensuring the
highest possible displacements are determined by the extreme surfaces
technique and the finite-element method. The simulated displacements for optimal orientations of LiNbO 3 and LiTaO 3 plates are compared with
those obtained experimentally for manufactured LiNbO 3 and LiTaO 3 actuators, whose orientations are not optimal. As is shown, the optimal configuration of the actuator allows us to significantly increase its displacement
for both LiNbO 3 and LiTaO 3 specimens.
期刊介绍：
Journal of Sensors and Sensor Systems (JSSS) is an international open-access journal dedicated to science, application, and advancement of sensors and sensors as part of measurement systems. The emphasis is on sensor principles and phenomena, measuring systems, sensor technologies, and applications. The goal of JSSS is to provide a platform for scientists and professionals in academia – as well as for developers, engineers, and users – to discuss new developments and advancements in sensors and sensor systems.
