Piezoelectric Laminates,han a hundred ferroelectric materials are known. Conventional ferroelectric polycrystals are ceramics or natural crystals, which are crystalline and brittle. The sensors or actuators developed from these types of materials are point sensors/actuators. A point sensor/actuator, such as an acceleromete

,Electrorheological Fluids — Materials and Applications,if the solidification might be accomplished at constant temperature or pressure and there will probably be no response. If you probe further and see if the engineer can suggest a way to control the shear stress vs. shear rate behavior, a continued look of bewilderment will be the response.

Piezoelectric Wafers for Reducing the Structure Vibrations,is an equivalence between an electric field and a strain in the structure. The first works on the subject were due to P. Langevin for quartz (P. Langevin,1918), but it was only in the early seventies that the use of polyvinil-di-fluor (PVDF in brief) spawned a generalized use of this effect in mecha

Intelligent Sensor Systems for Underwater Acoustic Applications, a manipulation of these waves can be performed. This is in contrast to smart vibration sensors that detect the modal or displacement characteristics of a structure. Intelligent sensors can characterize an acoustic pressure field into individual field components for signal processing purposes.

Active Vibration Control of Axially Moving Continua,ns and belts, aerial cable tramways, textile and fiberglass fibers, pipes conveying fluids, and oil lines (Mote, 1972). Vibration of axially moving continua limits their utility in many applications, and particularly high speed, precision systems. Flutter of a computer tape causes track misregistrat

Model Refinement and Damage Location for Intelligent Structures,ISS would adapt its dynamic characteristics to meet performance objectives at any instant. Therefore, ISS have a tremendous potential for a wide range of structural applications in which efficient integrated systems are necessary, from large space structures to low noise emission submarines. To real
