The performance and applications of PZT composite transducer with 3-3 connectivity.
The performance of 3-3 connectivity composite piezoelectric transducers is discussed. This type of transducer has been successfully used in ultrasonic imaging (frequency range: 150~600 kHz). Using a simple hardware system, this type of transducer can recognize a very thin aluminum plank (6 mm in thickness) in water, and it can clearly recognize a multilayer body.
