‘Smart materials’ (also described as intelligent, sense-able, multifunctional, or adaptive materials) can be thought of as material systems which manifest their own functions intelligently depending on sensed environmental changes. They are modeled on biological systems with: (i) sensors acting as a nervous system (right-hand full circle in Fig. 1), (ii) actuators acting like muscles (left-hand full circle in Fig. 1), and (iii) real-time processors acting as a brain to control the system (lowest full circle in Fig. 1). The different classes of structures relating to the technology are given in Fig. 1. Of particular interest are the following: (i) Type I: passive sensory structures, which possess a structurally integrated microsensor system for determining the state of the structure and possibly the environment in which it is operating; (ii) Type II: reactive smart structures, which have a nervous system and an actuator control real-time processor systems loop to effect a change in some aspect (stiffness, shape, position, orientation, or velocity); and (iii) Type III: intelligent structures, which are capable of adaptive learning.
