Electric polarization in a substance (especially certain crystals) resulting from the application of mechanical stress.
- ‘During the week, floating tiles would generate energy through piezoelectricity, a 19 th-century technology that is used to power quartz watches.’
- ‘The motile mechanism of the outer hair cell is analogous to piezoelectricity in that it is based on direct electromechanical coupling, in which charge is transferred across the membrane.’
- ‘Electricity as a natural phenomenon shows up in many forms, including piezoelectricity, static electricity, atmospheric effects, and cosmic rays.’
- ‘Thus, electrical and mechanical changes are coupled, analogous to piezoelectricity.’
- ‘Our observation confirms that prestin is indeed a motor protein based on piezoelectricity.’
Late 19th century: from Greek piezein press, squeeze + electricity.
