PZT Material:
- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.
- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.
- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
