piezoelectric effect oskar-e fešârbarqi Fr.: effet piézoélectrique The property exhibited by some crystals (notably quartz) that develop an electric charge or potential difference across them when subjected to mechanical strain; and conversely produce mechanical forces when a voltage is applied to them in a suitable manner. From piezo-, from Gk. piezein "to press tight" + → electric; → effect. oskar, → effect; fešârbarqi pertaining to fešârbarq, from fešâr, → pressure, + barq, → electricity. |
