压电效应是固态物理学中的一个关键现象，具有重要的技术相关性。然而，在教学过程中，它往往缺乏历史背景或与微观晶体结构的明确联系，这意味着一个关键的理解层面尚未被充分挖掘。本研究将压电效应的发现历史与其物理描述结合在一个教学上连贯的框架内。基于雅克·居里和皮埃尔·居里兄弟（1880-1882年）的工作，本研究展示了对热释电效应的研究如何导致了对电气石和石英等半面体晶体中由机械压缩引起的极化的识别。从早期定性实验到首次定量测定压电常数的过程，本文以结构化的方式进行了追溯。以低温石英为例，压电效应的微观原因被归因于正硅酸盐离子四面体网络中硅离子和氧离子的不对称位移。这导致晶格中未补偿的偶极矩形成宏观极化。直接压电效应和逆压电效应被定性区分，并在机电耦合的背景下进行了讨论。本文面向物理学和工程学专业的学生以及讲师。它被构思为一篇教学性综述文章（教程文章），并作为压电效应的物理和历史基础的结构化导论。
英文摘要
Piezoelectricity is a key phenomenon in solid-state physics and has significant technological relevance. In teaching, however, it is often treated either without a historical context or an explicit link to the microscopic crystal structure, meaning that a crucial level of understanding remains untapped. This study combines the history of the discovery of piezoelectricity with its physical description within a didactically coherent framework. Building on the work of the brothers, Jacques and Pierre Curie (1880 - 1882), it demonstrated how investigations into pyroelectricity led to the identification of polarization induced by mechanical compression in hemihedral crystals such as tourmaline and quartz. The development from early qualitative experiments towards the first quantitative determination of piezoelectric constants is traced in a structured manner. Using low quartz as an example, the microscopic cause of piezoelectricity was attributed to the asymmetric displacements of silicon and oxygen ions within the orthosilicate ion tetrahedral network. This leads to the formation of macroscopic polarization owing to uncompensated dipole moments in the crystal lattice. The direct and reciprocal piezoelectric effects are qualitatively distinguished and discussed in the context of mechanical-electrical coupling. The article is aimed at students in physics and engineering as well as lecturers. It was conceived as a didactic review article (tutorial article) and serves as a structured introduction to the physical and historical foundations of piezoelectricity.
