High-performance piezoelectric actuators piezoelectric Driver Piezo Actuator for Micro Displacement Driving Device
Piezo Actuator
Piezo actuators are made from a sandwiched pair of piezoelectric elements which can expand and contract in length. When used as a sensor,bending causes one side to go into tension and the other into compression, and having a response frequency in the audible range permits the bimorph element to be used as a high sensitivity sound sensor. When used as an actuator, an electrical input results in a bending force which can be used as a switching element in a wide range of applications.

SINOCERA PIEZOTRONICS, INC was established in 2001, with 34.6 million yuan registered capital and factory area more than 9000m2.We are mainly engaged in the development, production, and sales of high-performance piezoelectric ceramic materials, piezoelectric sensors and dynamic testing instruments.
We are committed to the research and application development of high performance of piezoelectric ceramic materials. Successfully developed all kinds of different performance piezoelectric ceramic products, and the piezoelectric ceramic material ultra-high piezoelectric constant (D33 >800PC) has reached the international advanced level.
Our products has get a good reputation all over the world, for example, our professional D33 Test Meter was very popular. Also we have a good quality control system, have passed ISO9001. Some of the products have received the certificate for measurement assurance and the explosion proof certificate, Rohs certificate, CE certificate and so on.
