This volume contains a collection of 40 papers from two symposia: Advanced Dielectric Materials and Multilayer Electronic Devices and High Strain Piezoelectric Materials, Devices and Applications. Topics include fundamental and historical perspectives of dielectric materials; relaxor materials and devices; high strain piezoelectric devices; advanced aspects of powder preparation, characterization, and properties; thin films; materials for low and high frequency applications; processing-structure-property-relationships; and future applications. Proceedings of the symposium held at the 105th Annual Meeting of The American Ceramic Society, April 27-30, 2003, in Nashville, Tennessee; Ceramic Transactions, Volume 150.
