I am trying to model a sensor made using a cylindrically polarized ring of PZT, using the acoustics module. I am applying a background pressure field and want to measure the voltage produced on the outside of the ring (the inner surface is ground, and I want to outer surface to be covered with 4 electrodes, one in each quadrant). I eventually want to do this for a range of frequencies to determine the resonant frequency of the sensor. Any suggestions on how to proceed?
I cant figure out how to ensure that the voltage is equal across the surface of the electrode. I have tried defining them as floating potentials (acoustic-piezoelectric interaction, frequency domain), but I am still seeing a voltage gradient across the surface. Some help on this would be greatly appreciated.
I should be able to upload my model if that would help, just let me know.
