“SMART MATERIALS” ABSTRACT The world has undergone two materials ages‚ the plastics age and the composite age‚ during the past centuries. In the midst of these two ages a new era has developed. This is the smart materials era. According to early definitions‚ smart materials are materials that respond to their environments in a timely manner. The definition of smart materials has been expanded to materials that receive‚ transmit or process a stimulus and respond

SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must
