Ferroelectrics of piezo sphere sensor
Waveforms include inkjet, non-inkjet (channel 5 waveform) and wait waveform (channel 1, 3, 4, and 6 waveforms). Channels 2, 5, and 8 are active. The channel of piezoelectric ultrasonic welding is waiting. In order to ensure that the printer can work properly, the driver circuit must also meet certain power and drive pulse width requirements. The maximum output voltage of ±100 V is selected here, and the single output current piezo ceramic ultrasonic cleaning is greater than 20 mA. The driving pulse width is continuously adjustable within 5 to 200μs.
Ferroelectrics of piezo sphere sensor are an important class of functional materials that are capable of spontaneous polarization, and spontaneous polarization can rotate under the action of an electric field. This is the essential characteristic of ferroelectrics. Ferroelectrics of piezoelectric disc crystal have good properties such as ferroelectricity, piezoelectricity, pyroelectricity, electro-optic and nonlinear optics.
Piezoelectric ceramics is a class of ferroelectrics with excellent piezoelectric properties. Piezo sphere transducer is an information-oriented ceramic material that converts mechanical properties and electrical energy to each other. Piezoelectric ceramics have not only piezoelectric effect but also dielectricity, ferroelectricity, etc. Therefore, piezoelectric ceramics have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, and display devices.
However, piezo tubes transducer is in practical components, different applications require different performance parameters for piezoelectric ceramics, which obliges people to make corresponding modifications to piezoelectric ceramic materials. With the development of modern electronics, information, and aerospace technologies, the development and exploration of piezoelectric ceramics with excellent performance has become a research hotspot in various countries.
