【Abstract】 The preparation of lateral model (d 31 ) piezoelectric actuator was reported in this paper.A high-steady piezoelectric ceramic with tungsten bronze structure was used as the basic material of the actuator,and its piezoelectric induced displacement curve was measured by using the principle of F-P interferometer as well as the lateral piezoelectric constant (d 31 ). As discussed,this kind of actuator features high linearity and small hysteresis between induced displacement and applied electric field,meanwhile its structure is simple and easy to be fabricated.This actuator should have its applications in field of precise machinery.更多还原
