摘要/Abstract

摘要： 本文基于铁电体的自发极化Ps在外电场、应力或温度作用下的变化面△Ps，引入组合功能效应的概念，利用厚膜和薄膜材料的叠层技术和集成工艺把功能陶瓷的多种特性组合起来，以设计和制备新型智能材料和器件．最近研制的热释电电压变压器的初步实验结果表明，这一设想是合理和可行的．

关键词: 诱导相变, 自发极化, 复合功能效应, 智能结构, 等效回路

Abstract: Based on the variation of spontaneous polarization Ps of ferroelectrics under applied electric field,temperature and stress,a concept of composite functional effect that different kinds of materials with different functional effects can be composed together to find a new material by multilayer and thin film integrated technologies was proposed to design new intelligent materials and devices. The principle demonstration and experimental results of a pyroelectric voltage transformer showed that this assumption is reasonable and feasible。

Key words: induced phase transition, spontaneous polarization, composite functional effects, smart structures, equivalent circuits
