The MEMS Module includes linear elastic and linear viscoelastic material models, but you can supplement it with the Nonlinear Structural Materials Module to also include nonlinear material models. Comsol mems tutorial your post in a legible manner.

MEMS Module

Please login with a confirmed email address before reporting spam. Piezoelectric Shear-Actuated Beam The model performs a static analysis on a piezoelectric actuator based on the comsol mems tutorial of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface.

Physics such as electromechanics, piezoelectricity, piezoresistivity, thermal-structure, and fluid-structure interactions can comsol mems tutorial modeled with the software. COMSOL offers the flexibility to evaluate a wide range of physical quantities, including predefined quantities like temperature, electric field, comsol mems tutorial stress tensor available through easy-to-use menusas well as arbitrary user-defined expressions.

The equations are then solved using the finite element method and a range of industrial strength solvers. Never invent acronyms and use as few acronyms as possible. Cosol and Accurate Measurement of Blood Viscosity. Thermal forces scale favorably in comparison to inertial forces.

For elastic vibrations and waves, perfectly matched layers PMLs provide state-of-the-art absorption of outgoing elastic energy. In addition, the favorable scaling of the electromagnetic forces enables efficient capacitive actuation that would not be possible on the macroscale.

Inspired by work done by V. You can include a variety of damping phenomena in your model: Piezoresistive pressure sensors were some of the first MEMS devices to be commercialized. The model solves the deformation of the beam under an applied voltage. Why do we have to disable terminal 3? You can fix this by comskl ‘F12’ on your keyboard, Coomsol ‘Document Mema and choosing ‘standards’ or the latest version listed if standards is not an option.


You can easily perform lumped parameter extraction of capacitance, impedance, and admittance, cmosol connect to external comsol mems tutorial circuits via SPICE netlists.

MEMS Software – For Microelectromechanical Systems Simulation

Thickness Shear Mode Quartz Oscillator AT cut quartz crystals are widely employed in a range of applications, from oscillators to microbalances.

Comsol mems tutorial model estimates how much current and increase in Try to catch typos. The moderators of the forums will remove any generally objectionable material as quickly as possible. This model shows how to simulate a comsol mems tutorial actuated surface micromachined accelerometer, using the Electromechanics Interface. One titorial device is the electrostatically controlled micromirror. Review your post before publishing it.

Thin-film damping is available on arbitrary surfaces in 3D and can be directly coupled to 3D solids.

This comsol mems tutorial application moves a beam by passing a current through it; the current generates heat, and the temperature increase leads to displacement through thermal expansion. You can fix this by pressing ‘F12’ on your keyboard, Selecting ‘Document Mode’ and choosing ‘standards’ or the latest version listed if standards is not an option.

If you are familiar with LaTeX, please use this to write mathematical equations. Bans and warnings issued to other users are considered personal information.

For their integration in microelectronic circuits, MEMS devices are bonded on printed circuit boards and connected with other devices. Prestressed Micromirror One method of creating spring-like structures or inducing curvature in thin structures is to plate them comsol mems tutorial substrates that are under the influence of residual stresses. It illustrates comsol mems tutorial fluid flow can deform solid structures and how to solve for the flow in a continuously deforming geometry.


Comsol mems tutorial elastic cantilever beam is one of the elementary structures used in MEMS designs. By talking comsol mems tutorial one of our sales representatives, tutoria, will get personalized recommendations and fully documented examples to help you get the most out of your evaluation and guide you to choose the best license option to suit your needs.

You will receive a response from a sales representative within one business day. Hence, they will not be held liable.

MEMS and Piezoelectric Device Models

Consequently, software specifically designed for MEMS simulation and modeling has never been more comsol mems tutorial. The epoxy polymers used for such applications are subject to moisture The FSI couplings appear on the boundaries between the fluid and the solid, and can include both fluid pressure and viscous forces, as well as momentum transfer from the solid to the fluid — bidirectional Comsol mems tutorial.

The model solves the deformation of the beam under an applied voltage. Deformation depends on the ambient pressure and temperature, on the materials used, and on any initial stresses in the material.

Piezoelectric Shear-Actuated Beam The model commsol a static analysis on a piezoelectric actuator based on the movement of a cantilever beam, using the Piezoelectric Devices predefined multiphysics interface.
