  • Shape Memory Alloys:
  • Magnetostrictive:
  • Shape Memory Polymers:

What is a smart material in DT?

Smart materials are materials that have one or more property that can be significantly altered in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields. E.g. Nitinol Wire, Thermochromic pigments, Thermochromic film.

What can photochromic materials be used for?
