How to simulate a Piezoelectric Micromachined Ultrasound Transducer (PMUT) device in OnScale

A piezoelectric micromachined ultrasound transducer, also called PMUT, is an electronic device capable to generate ultrasonic sound waves.

They have various applications:

For example, they can be used to measure a distance into a medical device for example.

The principle is quite simple

A small circular area build in piezzoelectric material vibrate very quickly under a voltage applied to it and generate such ultrasonic waves

So, how do you simulate such a device?

To simulate a PMUT device, I will use a software called OnScale, which is currently the best on the market to simulate such devices.

Here’s a video Tutorial:

In this video tutorial, you will learn:

• How to create a 2D axisymmetric model in OnScale
• How to generate the geometry of your model in the OnScale Designer mode using basic shapes
• How to assign time dependent loads and boundary conditions
• How to launch the Analysis and check the Results
