2) How to judge the positive and negative electrodes of piezoelectric ceramics?
Piezoelectric ceramics also have positive and negative electrodes. I believe that many people are very clear about this, but the method of judging it is basically that the lead will be drawn on both sides of the positive and negative electrodes. In the actual use process, There are more current to see how the final pointer swings. If it swings to the right, this shows that the entire red test lead is connected to the positive electrode of piezoelectric ceramic transducer, and if it is negative, it is connected to the black test lead.
3) Does the bonding of piezoelectric ceramics and metal substrates produce sound?
Piezoelectric ceramics piezo ceramics poling must be able to emit sound during the bonding process, and basically they have to be replaced with more things.
