How to simulate piezoelectric sens signal

Hi,

I'm trying to simulate piezoelectric sensor with drive and sens electrodes. I am able to use piezo (AlN) as drive by simply applying voltage difference between piezo material top and bottom surfaces. But how to extract piezo sens current (or dQ/dt) in Frequency Domain analysis from piezo sens surfaces? Do I have to add some electric circuit or additional metal electrodes?

Thanks.

Br,
Matti
