The recent increase in demand for sensors motivated development of new classes of multifunctional materials. Smart materials are recent class of multifunctional materials that undergo reversible extrinsic changes under application of external stimuli like pressure, temperature, electric/magnetic field, and stress. This ability for reversibility demonstrates the performance of these materials which in turn has led to the development of lighter, more energy-efficient innovative solutions for multipurpose applications. These multifunctional materials find application as sensors/actuators. The use of these materials and their structural characteristics up to this point has been well peer reviewed, but the relationship between sustainability considerations and the deployment of various grades of smart materials has received lesser attention. this paper attempts to draw a more significant relationship between smart materials and its notable applications through a detailed review of previous experimental, numerical, and conceptual studies, followed by an overview of their behavior and properties. Finally, some notable recent applications and influence of deployment areas of smart materials is discussed. This work lays a critical comparison between Shape Memory Alloy (SMA) and Piezoelectric (PZT) material behavior and properties.
