This paper presents different models and results of simulations of MEMS vibrating gyroscope in Matlab/SIMULINK environment. Each model is created with different approach, using different blocks and different physics. Therefore author presents his proposal of mathematical, electrical equivalent and physical models. Results obtained from these models can give some hints regarding design and dimensions of some crucial parts of MEMS gyroscope. Here, decoupled vibrating sensor is considered, which minimize drive and sense motion mutual influence.

This paper presents developed mathematical model of MEMS gyroscope created in Matlab/SIMULINK environment. The model can be very useful for calculating MEMS gyroscope geometrical parameters. These parameters play very significant role, because they have huge and direct impact on device response, performance and further possibilities of application. Results of simulations are presented in this article separately for drive and sense direction. In addition there are also results in frequency domain presented. With all these results we obtain quick overview of behavior this kind of MEMS device and response characteristics.

In this paper modelling and simulation of MEMS accelerometers in Matlab/SIMULINK environment are presented. Results of simulations of three different approaches: mathematical, electrical equivalent and physical models are compared with FEM accelerometer model created in COMSOL software. Results of simulations are analyzed for displacement response for two of the most popular spring geometries - folded and straight. Author takes into consideration crucial aspects of damping coefficients influence on accelerometer performance.

In the simulation of micro electro mechanical systems (MEMS) the calculation of electric fields plays an important role. In many cases electric fields near corners have to be calculated. Since in these cases the singular behavior has to be taken into account they deserve special attention. An augmented finite element approach is presented and applied to an electrostatic force microscope (EFM).
