INTRODUCTION: SMART MATERIALS

When something changes about a smart material, it changes too!

  • Smart materials are materials that have a property that can be significantly changed in a controlled way by external stimuli.

    • The external stimulus causing the change in the materials properties maybe stress e.g. bending or compression, change in light intensity, a temperature change, coming into contact with moisture, pH of a contact solution, electric potential difference (p.d./voltage, electric charge effect), or a strong magnetic field.

  • This means smart materials change in response to changing conditions in their surroundings or by the application of other direct influences.

  • The induced change in the property of the smart material might be in its electrical behaviour e.g. its electrical resistance, its mechanical-structural properties e.g. flexibility or strength, optical e.g. change in light transmittance, magnetic behaviour etc....

    • ... any of which change the way the material functions in response to the stimulus.

  • In a 'nutshell' smart materials can change their state, and therefore their properties, in response to an external stimulus.

  • There is now a huge variety of smart materials with different special properties that make a particular material well suited to a particular specific use.

  • Other materials described on this page are not strictly speaking 'smart materials', but they have been included under the more general heading 'materials science'.
