Unit 4: Smart materials

In order to understand smart material use in a product context, we must first step back and look at smart materials from a broad phenomenological perspective. 

D. Michelle Addington, Daniel L. Schodek

They will soon be in everything from computers to concrete bridges

W. Wayt Gibbs

W ARM-UP

  1. Think of as many words as possible related to smart materials.

  2. Work with a partner or small group. Your topic is "Application of Smart materials". List as many ideas as you can in five minutes.

Aerospace, ..., ...,

  1. Read the suggested example of the smart materials application and try to give your own examples.

A useful example is during an earthquake, magneto-rheostatic fluid inside the dampers will change from solid to liquid and back as tremors activate a magnetic force inside the damper. Using these dampers in buildings and on bridges will create smart structures that automatically react to seismic activity. This will limit the amount of damage caused by earthquakes.  With this example we demonstrate that with the smart materials we are preparing for the future security.

  1. Match the words/phrases (1-6) with the pictures (a-f).

print material, metal foam, ferro fluid, aerogel, amorphous alloy, nanotube

Where can these materials be used?

  1. Discuss the following questions.

  1. Do you think the materials are clever, fashionable, or formal?

  2. What is a smart material?

  3. The scientists often use the words "smart", "intelligent" , "designed" and "responsive" combining them with the word "materials". Do they mean the same when they say "smart materials", "intelligent materials", " designed materials", "responsive materials"? What do they mean? Why do the scientists often substitute these phrases?

  4. Think of examples from nature that are like smart materials, for example, things that can change shape or color, or repair themselves.

  5. When was the first smart material discovered and who was it discovered by?

  6. Would you use smart materials? Why (not)?

READING

  1. Underline the stressed sound in each word as in the example. Practise reading.

Clutches, piezoelectric, substance, reversed, valves, vibration, vehicles, viscosity, magneto-rheostatic, electro-rheostatic, pseudo-elasticity
