1. Smart materials Smart materials are reactive materials. Their properties can be changed by exposure to stimuli, such as electric and magnetic fields, stress, moisture and temperature. https://www.youtube.com/watch?v=3Tp6IC_SXu0 http://www.bbc.co.uk/schools/gcsebitesize/design/resistantmaterials/m aterialsmaterialsrev5.shtml https://www.youtube.com/watch?v=FgrIDibPmJo Smart Materials

2. Modern Materials Steel FrameAluminium Frame Carbon Fibre Frame

3. Thermochromic Inks/ pigments that change colour with temperature Useful on marketing materials Interesting gimmicks ! Has your egg been hot enough for long enough? A 2d temperature gauge

4. Polymorph Supplied as granules When heated to 62 degrees or above in water they form a ply able solid Useful for forming : handles/grips Complex shapes Prototype patterns for casting or moulding Completing complex assemblies

5. Smart Springs Made from any alloy of nickel/titanium At room temperature the spring is fully extended manually By heating up or applying a small electric current the spring will return to its original position and carry a load Possible applications Emergency shutter in case of fire of: Bin lids Blinds windows

6. Photochromic Materials Materials that change colour when exposed to light Possible Applications: energy-efficient windows that switch from transparent to opaque spontaneously upon exposure to increasing levels of sunlight

10. Nanomaterials Nanoparticles improve the mechanical properties of a material, such as stiffness or elasticity. When incorporated into polymers, they can be used as lightweight replacements for metals. https://www.youtube.com/watch?v=WOqEk440JZ8 https://www.youtube.com/watch?v=a8FM9umJXvo
