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.
Piezoelectric materials generate an electrical charge in response to mechanical movement, or vice versa, produce mechanical movement in response to electrical input. This report discusses the basic concepts of piezoelectric transducers used as sensors and
Piezoelectric thin films can be deposited on semiconductor platforms (through a number of methods such as atomic-layer-deposition, sputtering, chemical vapor deposition (CVD), etc.) processes. Examples: aluminum nitride (AlN), zinc oxide (ZnO), lead zirconate titanate (PZT).
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

contribution to piezoelectricity. The fundamental structure–property mechanisms revealed in lead-containing piezoelectric materials can be also operational in lead-free systems and at a minimum, should be consid-ered as starting guidelines for the development of lead-free piezoelectrics from the aspects of composition modification, microstructu...
Piezoelectricity has been demonstrated qualitatively in approximately 1000 crystal materials. These include materials where piezoelectricity occurs naturally, and other single crystal and polycrystalline materials in which piezoelectricity can be induced by the application of high voltage or poling.
