Smart/intelligent systems is a primary technology for present and future applications in areas ranging from everyday life to aerospace missions, from civil to military environments, from robots to information technology. Smart materials are the critical foundation for high-performance smart devices, and smart devices are fundamental components for smart systems. The three cannot be separated. This book bridges the fields of smart materials, sensing and actuating devices, and intelligent systems, and provides an opportunity for researchers from all three arenas to channel information into a coherent, interdisciplinary community. Topics include: piezoelectric actuators; novel devices and systems; shape memory alloys and magnetostrictive devices; nanometer-scale processing and properties; piezoelectric materials; sensor materials and devices; and electroactive polymer actuators.

Microsystems are systems that integrate, on a chip or a package, one or more of many different categories of microdevices. As the past few decades were dominated by the development and rapid miniaturization of circuitry, the current and coming decades are witnessing a similar revolution in the miniaturization of sensors, actuators, and electronics; and communication, control and power devices. Applications ranging from biomedicine to warfare are driving rapid innovation and growth in the field, which is pushing this topic into graduate and undergraduate curricula in electrical, mechanical, and biomedical engineering.

Presenting unified coverage of the design and modeling of smart micro- and macrosystems, this book addresses fabrication issues and outlines the challenges faced by engineers working with smart sensors in a variety of applications. Part I deals with the fundamental concepts of a typical smart system and its constituent components. Preliminary fabrication and characterization concepts are introduced before design principles are discussed in detail. Part III presents a comprehensive account of the modeling of smart systems, smart sensors and actuators. Part IV builds upon the fundamental concepts to analyze fabrication techniques for silicon-based MEMS in more detail. Practicing engineers will benefit from the detailed assessment of applications in communications technology, aerospace, biomedical and mechanical engineering. The book provides an essential reference or textbook for graduates following a course in smart sensors, actuators and systems.

Smart/intelligent systems employ active materials as sensors/actuators to respond to environmental conditions for next-generation machines and structures - applications ranging from everyday life to space exploration missions, from civilian products to military needs, from robots to information/communication technology. It is not surprising, then, that the development of smart materials systems and structures demand higher performance sensors/actuators with new and reliable functions and a fully integrated composite system design. This requires the combination of active and passive materials systems, often including the coupling of relevant mechanical, electrical, magnetic, thermal or other physical/chemical properties. This book bridges the fields of smart materials, sensing and actuating devices, and intelligent/smart systems, and provides an opportunity for researchers from related disciplines to build an interdisciplinary research field and community. Topics include: ferroelectrics and piezoelectrics; nanomaterials and nanofabrication; shape-memory alloys and magnetomaterials; active polymers and soft matters; and other materials, devices and characterization.

Smart materials have been categorized employing taxonomical methods used in classification of cybernetics systems. This approach has allowed the systematization of the variety of smart materials (both developed and conceptualized) as well to substantiate the three-stage process of the materials’ making. This book proposes a phenomenological model describing smart materials.
