This book contains up-to-date information on the state of the art of research and applications in electro- and magnetorheology. A total of 130 papers are presented in four sections. The first section is devoted to the various applications of ER and MR fluids, like polishing, microfluidics, vibration control, robots, shock absorbers and dampers, MR and ER valves. The second part deals with the experimental characterization as well as the theoretical prediction of the mesostructure resulting from field-induced phase separation. The dynamics of phase separation is also included in this section. The third section is about the material properties; it includes papers on new compositions of ER or MR fluids, polymer blends, magneto- or electroactive elastomers and gels. The last section, about physical mechanisms, presents experiments and theories on the rheology of the fluids and its connection with microhydrodynamics and the structure of field-induced aggregates.
This book focuses on smart materials and structures, which are also referred to as intelligent, adaptive, active, sensory, and metamorphic. The ultimate goal is to develop biologically inspired multifunctional materials with the capability to adapt their structural characteristics, monitor their health condition, perform self-diagnosis and self-repair, morph their shape, and undergo significant controlled motion.
This volume covers the most recent progress of research work on electrorheological (ER) and magnetorheological (MR) industrial applications related to controllable damping, ER/MR fundamental mechanisms, and understanding the potential of new classes of field responsive materials.The proceedings have been selected for coverage in:• Materials Science Citation Index®• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences

ERMR 2006 included invited speakers, technical presentations, poster presentations, and a student paper competition. At the conference banquet, Dr. David Carlson of Lord Corporation addressed the conference attendees and gave a stirring speech on the history of ER and MR fluids, as well as current and future applications. A unique feature of the ERMR Conferences is that they comprehensively cover issues ranging from physics to chemistry to engineering applications of ER and MR materials held in a general session to enhance the interaction between the scientists and engineers. The sessions in ERMR 2006 were organized based into two Symposia: a) Materials and b) Applications. Topics covered in the Materials Symposium included: mechanisms, preparation, and characterization of ER and MR materials. Topics covered in the Applications Symposium included: ER and MR devices, control systems, system integration, and applications. This structure was implemented in order to enable interaction between attending scientists and engineers in both the Materials Symposium and the Applications Symposium, and to enhance the free flow of ideas, and the potential collaborative research opportunities.

Electrorheological (ER) and magnetorheological (MR) fluids, which can be transformed from the liquid state into the solid state in milliseconds by applying an electric or a magnetic field, are smart fluids having the potential to revolutionize several industrial sectors. The Seventh International Conference on Electrorheological Fluids and Magnetorheological Suspensions took place at a time when some MR and ER applications were beginning to appear on the market, making a notable impact on industries. Scientists and engineers in multidisciplinary areas came together to explore the state-of-the-art technology and identify thrust areas to be focused on.This volume of proceedings collects contributions from most leading experts in the field. It reviews the most recent MR and ER applications, discusses the materials technology, explores the basic science research on ER and MR fluids, and examines the novel properties of these fluids. It provides the most up-to-date and probably the best information about the area. It can serve as a stimulating and valuable reference for research workers and students in materials science, condensed matter physics, engineering, and chemistry. The valuable information not only reports on the leading edge of research and applications, but also provides an overview of the field.

Electrorheological (ER) fluids and magnetorheological (MR) suspensions show dramatic and reversible rheological changes when the electric or magnetic field is applied. Over the past several years, their performance and reliability have been significantly improved and their potential applications and acceptances have been widened. These fluids may make a tremendous impact on industry and technology.This volume contains a total of 107 papers which are most up to date and which give probably the best information on the state of the art of the ERF/MRS field. It covers the fields of material technology, mechanisms, bridging structure and properties on ER fluids, MR suspensions and ferrofluids, and the fields of their applications, i.e. damping devices, clutches, braking devices, actuators, optical devices, polishing devices and so on.
