The piezo has 2 layers and has a resonant frequency at 100KHz. If it were a single layer I would have a go at simulating it but as it has two, one on top of the other I wouldn't know where to begin. Could I treat it as single layer do you think? For example a single layer piezo might have a resonant frequency at 1MHz, if you put 2 together you get 100KHz.keith1200rs said:A piezo model is similar to a quartz crystal with series and parallel resonances. There are also resonances in other 'modes' e.g. In thickness mode if you are using lateral resonance. You can usually ignore those, but not always.
