压电效应
一种效应：当材料发生变形时会产生电场（电压）（正压电效应）；或者当施加电场时材料会发生变形（逆压电效应）。这些效应由 Jacques 和 Pierre Curie 发现。
压电材料可以是天然的（例如石英），也可以是人造的（例如压电陶瓷）。
对比磁致伸缩。
Piezoelectric effect
An effect whereby an electric field (voltage) is generated if a material is deformed (the direct piezoelectric effect) or whereby a material deforms if an electric field is applied (the inverse piezoelectric effect). These effects were discovered by Jacques and Pierre Curie.
Piezoelectric materials may be natural (e.g., quartz) or man made (e.g., piezoelectric ceramic).
