Embodiment 2

[0039] Piezoelectric ceramics are commonly used actuator materials. It deforms under the action of an electric field, and the strain electric field is basically linear under low electric field. However, when the electric field strength increases, the strain electric field deviates from the linear relationship due to the change of electroforming orientation, and there is obvious hysteresis. . Soft PZT piezoelectric ceramics such as PZT-5A, PZT-5H, PZN-PZT, and PMN-PZT are commonly used driver materials, and their piezoelectric properties are shown in Table 1. We choose 0.375PMN-0.625PZT piezoelectric ceramics according to requirements The material is a piezoelectric ceramic material.
