Book excerpt: This volume represents a record of the proceedings of the Symposium on Materials for Smart Systems which was held in conjunction with the 1994 Materials Research Society Fall Meeting in Boston, Massachusetts. The Symposium revolved primarily around the use of ferroelectrics, magnetostrictive materials, and shape memory materials in the design of compact sensors and actuators. Productive joint sessions were also held in the areas of ferroelectric films-based transducers and chemical sensors. Ninety-six oral presentations were scheduled over the course of three days, including twelve in a joint session with the Symposium on Ferroelectric Thin Films IV, and ten with the Symposium on Chemical Perspectives of Microelectronics Materials. In addition, 35 poster presentations were scheduled during one of the lively evening poster sessions. Of the seventy-three papers in this volume, twenty-five (or roughly 35%) came from outside the U.S. In the ferroelectric sections that follow, innovative work on new antiferroelectric- based actuators, SAW-based actuators and ferroelectric composites is presented. In addition, fundamental studies on the behavior of well-established piezoelectric compositions under severe mechanical or electrical drive conditions are discussed. Several papers highlight the incorporation of ferroelectric actuators into commercial products, including gyroscopes, actively damped automobile suspensions, and medical diagnostic equipment. Among the magnetostrictive materials covered are the high-power magnetostrictive materials, namely the rare-earth and rare-earth-iron alloys, which exhibit large strain from cryogenic temperatures to 250'C.
