Abstract
Piezoelectricity is the ability of some solid materials to convert a mechanical deformation into an electric charge and vise versa. In recent years, piezoelectric ceramics have gained great importance in high precision actuating and sensing applications. As a part of the IRIS (MSA-6) project, this research is aimed at building an understanding of these materials as well as their processing and characterization techniques. In order to achieve this objective, a combined theoretical and experimental study was conducted by doing the following: the design and construction of experimental facilities for processing and characterizing piezoceramics, the documentation of a detailed theoretical background on piezoelectric materials and the selection of the most suitable ceramic for the planned purpose. This was followed by the processing and characterization of ten batches of piezoceramics. This application-oriented research has established the required background and expertise that will make it possible to repeatedly process the piezoceramic PZT in our laboratory.
