When we take Data for piezoelectric nanogenerator measurement, what is the significance of Piezoelectric polarity issues?
for me, polarity means that if I switch the connector leads the device should reverse the sign of potential produced? why ?? and what is the significance? any paper in that category is welcome?

If you reverse the leads, you will get output that is 180 degrees out of phase. Usually it doesn't matter, it's still an A/C voltage that can be rectified and used.
