Modeling Piezoelectric Devices as Both Transmitters and Receivers
Application ID: 71111
Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect echoes.
This model demonstrates how a piezoelectric device can be modeled when acting as both a transmitter and a receiver using COMSOL Multiphysics®. The example uses a transient analysis when time of flight is an output of interest.

This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- Acoustics Module and
- AC/DC Module, MEMS Module, Plasma Module, or Semiconductor Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
