24 Φεβ 2012 · A piezoelectric transducer (also known as a piezoelectric sensor) is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge.
Figure 1.1 (a) The direct piezoelectric effect provides an electric charge upon application of a mechanical stress, whereas (b) the converse piezoelectric effect describes the situation where strain develops under an applied electric field.
A piezoelectric transducer (also known as a piezoelectric sensor) is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge.
Basic concepts of piezoelectricity are presented in Chap. 1 along with an introduction into the field of microgravimetric sensors; appendices A and B, at the end of the book, include fundamental concepts of electrostatics
The piezoelectric phenomenon is a complex one and covers concepts of electronics as well as most of the areas of classical physics such as: mechanics, elasticity and strength of materials, thermodynamics, acoustics. wave's propagation, optics, electrostatics, fluids dynamics, circuit theory, crystallography etc. Probably, only a few disciplines ...
2 Δεκ 2023 · Conversely, when an electric field is applied to a piezoelectric material, it causes a mechanical deformation, known as the converse piezoelectric effect. Piezoelectric Effect The piezoelectric effect is the direct interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry.
The book fills an urgent need for a unified source of information on piezoelectric devices and their astounding variety of existing and emerging applications. Some of the chapters focus more on the basic concepts of the different disciplines involved and are presented in a didactic manner.
