4. What are your predictions for the next ten years for instruments and switches of the car? Prepare a short report or presentation.

1. Do you think the materials are clever, fashionable or formal? Read the text about ‘Smart materials’ and check.


Smart – or shape memory – materials are an invention that has changed the world of engineering. There are two types of them: metal alloys and plastic polymers. The metal alloys were made first and they are usually an expensive mixture of titanium and nickel. Shape memory materials are called ‘smart’ because they react to changes in their environment, for example:

· Plastics that return to their original shape when the temperature changes. One use is in surgery where plastic threads ‘remember’ the shape of a knot, react to the patient’s body temperature and make themselves into stitches.

· Metal alloys that have a ‘memory’ and can return to their original shape. They are used in medical implants. More everyday uses are for flexible spectacle frames and teeth braces.

· Solids that darken in sunlight, like the lenses in some sunglasses.

· Liquid crystals that change shape and colour. These have been used in climbing ropes that change colour if there is too much strain and weight on them.

The future of these materials and their possible uses is limited only by human imagination. One clever idea is that if cars were made of smart metal, a minor accident could be repaired by leaving the car in the sun!
