Piezoelectricity - Wikipedia
网页Piezoelectricity (/ ˌpiːzoʊ -, ˌpiːtsoʊ -, paɪˌiːzoʊ -/, US: / piˌeɪzoʊ -, piˌeɪtsoʊ -/) [1] 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.

Piezoelectricity and the Piezoelectric Effect
网页2023年12月2日 · The piezoelectric effect is the direct interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. The effect occurs in both natural and synthetic materials.
Piezoelectricity - How does it work? | What is it used for?
网页2022年5月21日 · Piezoelectricity (also called the piezoelectric effect) is the appearance of an electrical potential (a voltage, in other words) across the sides of a crystal when you subject it to mechanical stress (by squeezing it).
Piezoelectric Effect - an overview | ScienceDirect Topics
网页When the piezotronic material is forced by the mechanical stress, it generates a temporary electricity which is referred as direct piezoelectric effect. In addition, when the external voltage is applied, the materials will be deformed, which is …
