COMSOL Day: Electronic Devices

See what is possible with multiphysics simulation

Electronic components have been increasingly miniaturized and, as a result, portable electronic devices have become as powerful as mainframe computers were a decade ago. Many of today's portable devices also include a wide range of built-in sensors and actuators. To account for this advanced complexity when developing these devices, using multiphysics modeling that includes the effects of heat transfer, thermal expansion, elastic wave propagation, piezoelectricity, and electromagnetic fields has become increasingly important. The COMSOL Multiphysics® simulation software platform includes dedicated interfaces and multiphysics couplings that account for these phenomena, enabling you to build high-fidelity models of electronic components and devices.

Join us for COMSOL Day: Electronic Devices to learn from keynote talks and technical presentations about the benefits of using multiphysics simulation to study and design electronic components and devices. We will also give an overview of the relevant features in COMSOL Multiphysics® and demonstrate how the software can be used across large development teams.

Welcoming Remarks
11:15 a.m.

Modeling and simulation are essential to research and development (R&D) within the ever-changing electronics industry. In particular, multiphysics modeling platforms that are able to describe coupled phenomena, such as couplings between structural mechanics, heat transfer, fluid flow, and electromagnetic fields, are critical for accurate and realistic simulations. Furthermore, the ability for modeling experts to create simulation apps has become important, as it makes it possible for multiphysics modeling to reach more communities of engineers and scientists.

In this session, we will give an overview of the latest trends in modeling electronic devices, using models and apps within COMSOL Multiphysics® as examples. We will also show you how COMSOL® enables larger teams of engineers and scientists to collaborate on models and apps for their R&D projects.

Touchscreens and Other Capacitive Devices

Capacitive sensing is used in many applications, including proximity, pressure, displacement, position, and acceleration sensors. COMSOL Multiphysics® is widely used for the design and optimization of technologies that use such sensors, such as touchscreens.

The design of capacitive devices is elevated by models that couple electromagnetic fields, heat transfer, and structural mechanics, i.e., multiphysics models. These models can be used to optimize the response of touchscreens for different designs, uses, conditions, and touches. The unique ability to create simulation apps with the Application Builder enables developers to enhance their workflow by sharing these apps with colleagues and customers to quickly review designs.

Join us for this session to learn more about the multiphysics modeling of capacitive devices. We will give you an overview of the relevant capabilities in COMSOL Multiphysics® and demonstrate how to create models and simulation apps.

Modeling of Piezoelectric Acoustics

The miniaturization of electronic devices often requires the use of piezoelectric transducers and speakers in order to generate sound and ultrasound. There is a wide range of applications, from sonars for the detection of ships and submarines to microspeakers in cell phones.

For many years, COMSOL Multiphysics® has been essential in the modeling and simulation of piezoelectric devices due to its capability to couple electromagnetic fields with structural mechanics and heat transfer. The latest release of the software includes predefined formulations for the modeling of piezoelectricity as well as elastic waves in solids coupled with pressure wave propagation in fluids.

In this session, we will demonstrate the new multiphysics interfaces for piezoelectric waves in the time domain and a full vibroacoustics analysis involving piezoelectric devices.

Thermal Management for Electronics

The ability to dissipate heat is one of the most important features of modern electronic devices and is usually a limiting factor in the miniaturization of these devices.

COMSOL Multiphysics® includes functionality for heat transfer through conduction, convection, and radiation. Its ability to treat conjugate heat transfer, including laminar and turbulent flow as well as surface-to-surface radiation, has made it one of the major tools for the design and optimization of thermal management systems in electronics. Its unique multiphysics modeling capabilities also enable the study of thermoelectric effects as well as thermal–structural effects, such as thermal expansion. The latest version of the software features ready-made formulations for accurate phase transition, which can be used, for example, for the modeling of heat pipes.

In this session, we will demonstrate how to create models and apps for conjugate heat transfer in electronic devices. We will also give a general overview of the software’s capabilities for multiphysics modeling, including heat transfer as one of the modeled phenomena.

High-Frequency Electronics

The COMSOL Multiphysics® add-on products include the RF Module, Wave Optics Module, and Ray Optics Module, all of which can be used to design and optimize devices that involve high-frequency electromagnetic fields. The applications of these modules range from the design of optoelectronic waveguides to the reduction of reflection losses in 5G device connectors.

The unique multiphysics modeling capabilities of the COMSOL® software allow for the creation of accurate models that include thermal and structural effects in high-frequency electromagnetics, for example, stress–optical effects in photonic devices and thermal expansion in cavity filters.

Join us in this session to learn more about the COMSOL® software's multiphysics capabilities for modeling integrated antennas, waveguides, filters, connectors, and other high-frequency electromagnetic devices.

Parallel Session

Modern electronic devices are packed with MEMS actuators and sensors. The COMSOL® software's modeling capabilities have made it an in-demand tool for designing and optimizing MEMS devices.

The latest version of the software, including its dedicated MEMS Module add-on, features ready-made functionality for modeling electromechanics, electrostriction, magnetomechanics, and magnetostriction. In addition, the software includes unique modeling interfaces for multiphysics phenomena that are important for the study of MEMS devices, such as piezoelectric waves, piezoelectricity, electrothermal expansion, and fluid–structure interaction, to mention a few.

In this session, we will introduce the MEMS Module by summarizing its features and demonstrating examples that analyze MEMS sensors and actuators.


Semiconductors are building block in electronic devices. The COMSOL® software is able to describe a variety of devices, including:

  • Bipolar transistors
  • Metal-semiconductor field-effect transistors (MESFETs)
  • Metal-oxide-semiconductor field-effect transistors (MOSFETs)
  • Insulated-gate bipolar transistors (IGBTs)
  • Schottky diodes
