Abstract:

In this study, a novel piezoelectric actuator structure -4-9-9-14 piezoelectric actuator is constructed and it is made of piezoelectric buzzer to drive a piezoelectric actuated stage. The 4-9-9-14 piezoelectric actuator offers a better balanced capability of forward rotation and reverse rotation than the conventional edge-driving piezoelectric actuator. According to the rotational speed experiment, the CW/CCW ratio of the 4-9-9-14 piezoelectric actuator is probably 1: 0.8. The movement of the piezoelectric actuated stage is read and analyzed by means of data acquisition card and LabVIEW software operating in conjunction with a linear encoder. In a natural environment, plenty of noise interferes with linear encoder signals and results in erroneous addition performed by a counter. Therefore, the LabVIEW program set forth the means of filtering and the method for retrieving a correct position signal. The piezoelectric actuated stage by using 4-9-9-14 piezoelectric actuator can be expanded and applied easily to a longer distance moved stage.
