Smart/intelligent material systems utilize active materials as sensors/actuators to sense and respond to their environmental condition changes for more advanced next-generation machines and structures. The development of smart material systems and structures need more high-performance, functional sensor/actuator technology, 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 volume spans nearly all subfields of smart materials and devices and reflects the state of advancement of those materials research areas-in the field of electroceramics, emphasis is placed on improved processing-property relations, while in the "younger" fields of polymeric smart materials and ferromagnetic shape memory alloys (FSMAs), fundamental presentation predominates. Promising applications of smart materials and systems appear to combine multifunctional sensors and MEMS, e.g., for vibration control through PZT-bimorphs and stress control through high-sensitivity magnetostrictive sensor/actuator devices. Other applications focus on air environmental gas monitoring combining the MEMS environmental sensor and the internet, in vivo sensing through self-organized implantable polymer sensors, and SAW devices featuring wireless sensing and structure health monitoring. All demonstrate the multitude of applications that are feasible through the combination of sensor and actuator functions of smart materials. Topics include: ferroelectric and piezoelectric materials and devices; shape memory alloys; electroactive polymers; ferroelectric, piezoelectric and dielectric materials and devices; carbon nanotube, sensor and magnetic-based materials; photonic, optic and other novel materials; active materials systems and MEMS; magnetic and metallic-based smart materials; materials and devices for smart systems; and sensor materials and devices.
