Design and Simulation of a MEMS Torsional Micromirror

Article Preview

Abstract:

In this paper, we designed an electrostatic driving MEMS torsional micromirror. The operation principle of the torsional micromirror is analyzed. Based on the analysis, a set of optimized design parameters of the micromirror is suggested. The design optimization of the micromirror is also performed with MathCAD software. At last an ANSYS simulation is achieved in the paper, which proves that the micromirror can provide a maximum workable torsional angle rotation of ±0.55º with corresponding driving voltage of 17.5V.
