Smart Materials

• Smart Material - material that will react to a change in the environment
• Thermochromic Pigments

  • change when simulated by heat - pigment colour change
• Photochromic Pigments

  • change when stimulated by light - pigment colour changes
• Shape Memory Alloys

  • change when stimulated by heat
  • when heated goes to original shape
• Quantum Tunnelling composite

  • change when stimulated by pressure
  • only conductors when stimulated by pressure
