This piezoelectric ceramic material is between PZT8 and PZT5, taking into account the characteristics of both. It has high sensitivity and low dielectric loss. It is suitable for dual purpose transducers with low emission power and can be used as both receivers. At present, ultrasonic atomization transducers produced using this piezoelectric ceramic material have been put into mass production.
Piezoelectric ceramics, also known as transducer plates, are an indispensable and important component in the field of modern electronic technology. Piezoelectric ceramics are widely used in modern communication, radar, sonar, automatic measurement and control, ultrasonic energy conversion, ignition and detonation, ultrasonic sterilization, ultrasonic power, and other fields. At present, the development of piezoelectric ceramic materials and their applications in China is still in the development stage, and the development of this industry will have broad prospects.
When voltage is applied to piezoelectric ceramics, mechanical deformation occurs with changes in voltage and frequency. On the other hand, when piezoelectric ceramics are vibrated, an electric charge is generated. Using this principle, when an electric signal is applied to a vibrator composed of two piezoelectric ceramics or one piezoelectric ceramic and a metal sheet, called a dual piezoelectric chip element, ultrasonic waves are emitted due to bending vibration. On the contrary, when ultrasonic vibration is applied to a dual piezoelectric chip component, an electrical signal is generated. Based on the above effects, piezoelectric ceramics can be used as ultrasonic sensors.
