The document discusses smart materials and their classification and applications. It defines smart materials as materials that can sense and react to environmental stimuli in a controlled way. It provides a SMART acronym to describe the characteristics of smart materials and classifies common smart materials into types based on their input and output, including piezoelectric, electrostrictive, magnetostrictive, thermoelectric, and shape memory alloys. Examples of applications mentioned include smart fabric, aircraft, medical devices, robotics, and more.
