what's piezo inkjet?
Waveforms include piezo inkjet, non-inkjet, and wait waveforms (channels 1, 3, 4, and 6), where the channel of piezo cylinder transducer is in the active state and the rest of the channels are in the wait state. In order to ensure that the printer can work properly, the piezoelectric ceramic crystalmust also meet certain power and drive pulse width requirements. The maximum output voltage of ±100 V is selected here, and the single output current is greater than 20 mA. The driving pulse width is continuously adjustable within 5 to 200 μs.
Ferroelectrics ceramics 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. Piezoelectric energy harvesting is the essential characteristic of ferroelectrics. Ferroelectrics have good properties such as ferroelectricity, piezoelectricity, electro-optic and nonlinear optics. Piezoelectric ceramics is a class of ferroelectrics with excellent piezoelectric properties. Piezo disc element crystal 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 of piezoelectric firm actuator have been widely used in the medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, and display devices. However, in the practical components,different applications require different performance parameters for piezoelectric ceramics, PZT material ultrasonic transducer 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.
