Titel
FEM simulation and its application in MEMS design
Abstract
This paper presents the simulated static and dynamic properties of a micro capacitive transducer by using commercial FEM software - ANSYS. Evaluation of the stress distribution in the stretched membrane of the transducer indicates that the location of the access holes plays an important role for reliable device fabrication and operation. Acoustic simulation shows that the pressure variation in the radiation field of a piston source can be explicitly demonstrated. Experiment results validate the effectiveness of FEM simulation as a useful tool for the design of MEMS devices and rough estimation of their properties.
