Abstract : This symposia presents the latest research in the area of smart materials and active materials for sensors and actuators components integrated into smart structures technology. The most notable shift in direction to the reported research activity is in the move toward macroscale embedded systems and mesoscale (10 (exp-6) to 10(exp-2) m)) integrated smart composites. Rather than discrete actuators or sensors, more attention is given to a composite material response: a slab of material that warps purposefully or changes its surface contour; or monitors its health locally; or alters its physical characteristics locally. Small scale architecture was presented as a means to achieve an engineered negative Poisson's ratio utilized to increase the sensitivity of hydrophones. New techniques of patterning and constructing submillimeter sensors, actuators and distributed control elements suggest many structural and medical applications for this technology. The level of integration in biological systems is far more advanced than in synthetic smart materials and systems. However, our evolving understanding of how biological organisms organize, create, and synthesize systems with smart functions has inspired the research community and already lead to biomimetic material systems. Concepts from biological systems can he used in the synthesis and design of the next generation of advanced materials which function as smart systems. Recent developments only promise the opportunities that lie ahead.
