Piezoelectric Displacement Transducer

Piezoelectric sensors are versatile tools for the measurement of various processes.

Piezoelectric displacement transducer.

Typically piezo contractors are flat components. The displacement of contracting actuators is based on the transverse piezoelectric effect whereby up to approx. The polarized pzt material piezo plates undergoes mechanical deformation under the applied electric field. Piezoelectric ultrasonic transducers are using the piezoelectric effect of piezoelectric materials.

Their displacement occurs perpendicularly to the polarization direction and to the electric field. 20 µm is nominally achieved. The piezoelectric material is one kind of. They are used for quality assurance process control and for research and development in many industries.

This is called the inverse piezoelectric effect. It is derived from the greek word πιέζειν. A transducer can be anything that converts one form of energy to another. Piezein which means to squeeze or.

Conversely the mechanical deformation. What is piezoelectric transducer. 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. 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.
