The need for new generation of advanced materials in modern applications has led to the development of the smart materials. The idea of smart materials originated in mid-1980s. Their perception implies an ability to be clever, active, and sophisticated. Smart materials are unique in that they exhibit different properties when there is change in their environment. They react to changes in temperature, stress, moisture, pressure, light, electric or magnetic field. This peculiar property makes them useful for certain applications. Their degree of smartness is dictated by their responsiveness to environmental stimuli. Structures that are made from smart materials are referred to as “smart structures”. There are different types of smart materials. Each type exhibits different characteristics that can be changed.

These are materials (mainly crystals) that produce electric voltage when stress is applied. Conversely, applying a voltage across a piezoelectric material causes a change in the shape.

Electrostrictive Electrostriction is present in dielectric materials such as lead magnesium niobate (PMN).
