  This is the era of smart technology. People are becoming smart,
intelligent and dependent day by day and it is the duty of
engineers to make a common man’s life smarter and easier. This
duty was bestowed upon them by necessity and now it has been
successfully fulfilled by the introduction of smart materials and
composites.
   Composites are materials manufactured by combining any two
materials to achieve the unachievable properties of metal alloys
and smart materials are materials that has intrinsic or extrinsic
capabilities to respond to an external stimulus in a functionally
useful manner. The combination of these two materials give rise
to smart composites.
   In this paper, we are going to give introduction about
composites and smart materials and explain about various types
of smart materials, elaborated on shape memory alloys (SMA),
applications of SMA, explanation about stents and it’s
breakthroughs and finally, merits and demerits of the application.
