  • Smart materials
    • Shape memory alloys
      • Used in spectacle frames as the crystal structure of this composite, once deformed can regain or 'remember' its original shape.
      • Advantages
        • Superelasticity- extremely flexible so can be bent and 'sat on'.
        • Immediately recovers original shape.
        • Lightweight and durable.
      • Disadvantages
        • Not unbreakable.
        • More expensive than similar polymer frames.
    • Smart fluid/oils/grease
      • Advantages
        • Improves handling and road-holding as it adapts to the road.
        • Better and faster control.
      • Disadvantages
        • More expensive than traditional systems.
      • Used in car's suspension system to dampen the ride depending upon road conditions.
