Piezoelectric ceramic materials - a success story — •Dieter Sporn1, Andreas Schönecker2, Bernhard Brunner1, and Horst Beige3 — 1Fraunhofer-Institut fuer Silicatforschung, Neunerplatz 2, 97082 Wuerzburg — 2Fraunhofer-Institut fuer Keramische Technologie und Systeme, Winterbergstrasse 28, 01277 Dresden — 3Martin-Luther-Universität Halle-Wittenberg, Institut fuer Physik, Friedemann-Bach-Platz 6, 06108 Halle
The development of piezoelectric ceramic materials in the last decade offered a huge number of new applications. This can be shown by market numbers: the world wide market volume doubled from 2001 to 2006! This was driven by growing demands concerning of precise controls of structures and components, monitoring and adaptive systems, control of ignition points in engines, etc.
The success of the piezoelectric ceramics is based by tremendous efforts in material design, new compositions and new shaping opportunities. Beside commonly used buld materials it is evident, that piezoelectric films and fibers opened new applications. The development and the understandig of such structures is based on close cooperations between chemists, material scientists, physicists and engineers. One of the recently important issues is the search of new, lead-free compositions with properties similar to them of so far used lead-containing compositions.
In this contribution the efforts of the last years will be demonstrated on the hand of selected isssues (piezoelectric films, piezoelectric fibers and new compositions).
