How do I develop MATLAB or SIMULINK model of Piezoelectric disk?

Hello All,

Hope you all doing well.

I am trying to build a model of piezoelectric disk shown as in image. I don't have any idea about how to do it??

I want to measure a voltage and current from the disk.

Thanks to all in advance.

Hi Shardul!

There are some related examples in MATLAB documentation which you can refer. There is an example which uses PDE toolbox to model a piezoelectric actuator, this might prove to be an interesting read:

Moreover, there is a "Piezo Stack" block in SimElectronics, which is one of the Physical modeling toolboxes. This block is not a piezo sensor but an actuator. Nevertheless I am sure you can find it useful. Refer to the following link for the documentation of this particular block:

For the general SimElectronics documentation and features, refer to:

Hope the above suggestions help!
