Ceramic Piezoelectric Element

Stress on ceramic element.
Ceramic piezoelectric element. The designations of soft and hard piezo ceramics refer to the mobility of the dipoles or domains and hence also to the polarization and depolarization behavior. Pi ceramic provides system solutions for. Pi ceramic provides a wide selection of piezoelectric ceramic materials based on modified lead zirconate titanate pzt and barium titanate. Pzt electronic ceramic co ltd is the expert of piezo ceramics we are real manufacture with 20years experiences in this field.
This includes piezoceramic components and elements as well as piezoelectric actuators. Certified in accordance with iso 9001 iso 14001 and ohsas 18001 pi ceramic is one of the world s market lead ers for piezoelectric actuators and sensors. Piezoelectric ceramic components are electromechanical transducers. Equipment for ceramic production in house.
The variation in the length of the element is called residual polarization fig. They are used for quality assurance process control and for research and development in many industries. Piezoelectric ceramic rectangular component. Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals certain ceramics and biological matter such as bone dna and various proteins in response to applied mechanical stress the word piezoelectricity means electricity resulting from pressure and latent heat.
Pierre curie discovered the piezoelectric effect in 1880 but only in the 1950s did manufacturers begin to use the piezoelectric effect in industrial sensing applications. Even if the electric fi eld is eliminated the length of the piezoelectric ceramic element does not return to its original length in the nonpolarized state as a result of the 90 inversion of the zr ion or ti ion. Pi ceramic offers a large number of standard products and solutions based on piezo technology. Piezoelectric sensors are versatile tools for the measurement of various processes.
