Legislation against the use of lead initiated a search for lead-free piezoelectric ceramics. This project aims to derive guidelines for the development and implementation of this new class of materials. This project will utilise an analysis technique that allows elucidation of the origin of the high strain in piezoelectric materials. A separate analysis of the three known strain mechanisms in materials with coexisting phases will innovatively correlate theory and macroscopic observation with processes on the atomic scale. The quantification of the contribution of each mechanism will lead to new insights into the enhancement of sustainable functional materials.

禁止使用铅的立法开始了对无铅压电陶瓷的研究。该项目旨在为这种新型材料的开发和实施提供指导方针。该项目将利用一种分析技术，可以阐明压电材料中高应变的起源。对具有共存相的材料中的三种已知应变机制的单独分析将创新性地将理论和宏观观察与原子尺度上的过程联系起来。每种机制的量化贡献将为增强可持续功能材料带来新的见解。
