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
