If you are interested in modeling piezoelectric devices, then tune into this webinar with guest speaker Kyle Koppenhoefer of AltaSim Technologies.

Understanding the behavior of piezoelectric materials is critical for the successful development of devices (e.g., microelectronics, sensors, and transducers) and technologies (e.g., energy harvesting, joining of materials, and medical imaging).

Piezoelectric materials exhibit a linear electromechanical interaction between their mechanical and electrical state; however, the response is complex due to the anisotropic properties. Thus, numerical simulation is needed to predict the response of piezoelectric devices and quantify the effects of design changes.

In this webinar, AltaSim Technologies will draw on its experience in the computational analysis of a range of piezoelectric-based technologies to demonstrate ways in which these devices can be successfully analyzed and designed using COMSOL Multiphysics®.

You can ask questions at the end of the webinar during the Q&A session.

The tonpilz piezotransducer is used for low-frequency high-power sound emission. Simulation results show the voltage distribution in the piezoceramic rings, deformation in the massive ends, and pressure field underneath the transducer.
