I am looking for a model in Simulink that simulates the correct behaviour of a piezoelectric bender device that will be used as a micro-power generator.

I am trying to do the same thing and also the pressure loading of of a piezoelectric diaphragm. Simscape has the piezoelectric stack that I have been eying. It at least uses the constitutive equations. Thinking of picking up the gauntlet and writing my own.

The piezoelectric is actually from SimElectronics:

There are also rotary and linear piezo motors:

If you have a good grasp of the mathematical equations, you can create your own model using the Simscape language.

HTH,
