Answer to Question #240468 in Electrical Engineering for abhishek yadav

Question #240468
1. Design a piezoelectric stage capable of positioning with a 0.1nm resolution over a lum range. Assume that you have a power supply that can generate -10V to +100V and a 16 bit DAC board to control the power supply. You can choose any piezo material and geometry; however, you have to provide a reference (web-page, copy of the spec sheet) for the material of your choice. 16-bit board means that the control voltage minimum step is equal to the total range (110V in this case) divided by 216.
Expert's answer

In this design, the intention is to have 0.1nm resolution over a lum range. Assumption is made to the effect that:

·        Power supply that can generate -10V to +100V

·        A 16 bit DAC board

In the presented design of piezoelectric, a double layout structure of the -axis platform fixed on the -axis platform is adopted in the stage. Each axis mainly consists of actuator, guide mechanism, and displacement feedback apparatus. The image below shows the configuration and main components of the proposed stage:
