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. [ 2 ] .
How Do Piezoelectric Crystals Work? - Sciencing
网页By Isaiah David. The Piezoelectric Effect. Certain crystals such as quartz are piezoelectric. That means that when they are compressed or struck, they generate an electric charge. It works the other way as well: If you run an electric current through a piezoelectric crystal, the crystal changes shape slightly.
Piezoelectric Crystal - an overview | ScienceDirect Topics
网页A piezoelectric crystal is a type of crystal that changes its shape when an electric voltage is applied and generates electricity when pressure is applied. These crystals are used in various devices like filters, oscillators, pressure transducers, and ultrasound imagers.
