Abstract
The simulation of the actuator based on lithium niobate bimorph (bidomain) structure was carried out by the finite elements method. The calculated value of the displacement of the actuator was about 17.8 m at the voltage of 300 V. Based on results of simulation, an actuator was manufactured from the oppositely polarized plates of congruent lithium niobate bonded by diffusion of copper from the film placed between the plates. It was found that the displacement of this actuator is equal to 9 nm upon
the applied voltage of 1 V, and to 26.5 nm upon 3 V.
