Hi brother,
Smart materials have properties that react to changes in their environment. This means that one of their properties can be changed by an external condition, such as temperature, light, pressure or electricity. This change is reversible and can be repeated many times. For more clarification see attached file.

Smart materials are designed materials that have one or more than one properties that can be significantly changed in a controlled fashion by external way stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields

Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.
There are many groups of smart materials, each exhibiting particular properties which can be harnessed in a variety of high-tech and everyday applications. These include shape memory alloys, piezoelectric materials, magnetostrictive materials and chromic materials.
Piezoelectric materials produce a voltage when stress is applied and vice versa.
Large deformation can be induced or recovered in shape memory alloys by changing temperature or stress.
Magnetostrictive materials exhibit change in shape under the influence of magnetic field and also exhibit change in their magnetization under the influence of mechanical stress.
Chromic materials change colour in response to electrical, optical or thermal changes.
Smart materials can be defined as such those designed materials whose physical and chemical properties may be changed under the external application of Pressure, Temperature and electric or magnetic field.
