Definition of piezoelectricity in English:

piezoelectricity

Syllabification: pi·e·zo·e·lec·tric·i·ty
Pronunciation: /pēˌāzōˌilekˈtrisitē, pīˌēz-
 
/

noun

Electric polarization in a substance (especially certain crystals) resulting from the application of mechanical stress.

Piezoelectric substances are able to convert mechanical signals (such as sound waves) into electrical signals, and vice versa. They are therefore widely used in microphones, phonograph pickups, and earphones, and also to generate a spark for igniting gas

More example sentences
  • Electricity as a natural phenomenon shows up in many forms, including piezoelectricity, static electricity, atmospheric effects, and cosmic rays.
  • During the week, floating tiles would generate energy through piezoelectricity, a 19 th-century technology that is used to power quartz watches.
  • Thus, electrical and mechanical changes are coupled, analogous to piezoelectricity.

Origin

late 19th century: from Greek piezein 'press, squeeze' + electricity.

  • The structures are actuated with electrostatic, piezoelectric, or electromagnetic forces.
  • These substances are called piezomagnets, analogous to the terminology for piezoelectric crystals whose electrical conductivity changes when they are subjected to pressure.
