Smart Materials
A smart material is a material that will react to a change in the environment. This group of materials change when stimulated by heat, pressure, water, stress, PH Level, light or electricity.
Thermochromic pigments
Thermochromic pigments
- Thermochromic pigments change when stimulated by heat.
- The material is in a pigment form and is added to a variety of products.
- The pigment colour usually changes when they heat up or cool down.
- Commonly used in children’s thermometers, temperature indicators, children’s cutlery or novelty goods.
Photochromic pigments
Photochromic pigments
- Photochromic pigments change when stimulated by light.
- The material is in a pigment compound and is added to a variety of products.
- The pigment colour usually changes when exposed to UV light where they lighten or darken once the light is taken away.
- Commonly used in clothing, light changing paints and children’s novelty products.
Shape memory alloys (SMA)
Shape memory alloys (SMA)
- Shape memory alloys (SMA) change when stimulated by heat or electricity.
- The material is usually a thin metal wire or sheet.
- A shape memory alloys (SMA) can be heated then deformed.
- The shape will return to its original design when reheated.
- Commonly used in surgical stents, dental braces, glasses for frames and fire sprinklers.
Polycaprolactone (PCL)
Polycaprolactone (PCL)
- Polycaprolactone is commonly known as polymorph and changes when stimulated by heat.
- A white or coloured clear bead that can be easily moulded by hand.
- This smart material is fully biodegradable and can be moulded and remoulded in hot water.
- Commonly used in prototype modelling, hand-shaped products and jewellery.

Quantum tunnelling composite (QTC)
Quantum tunnelling composite (QTC)
- Quantum tunnelling composites change when stimulated by pressure.
- This polymer layer has suspended conductive nanoparticles that do not touch each other.
- This smart material is in a free-flowing state at rest but a conductor when stimulated by pressure.
- Commonly used in touch-sensitive mobile screens, wearable technology and speed controllers.
Piezoelectrical material
Piezoelectrical material
- Piezoelectrical materials change when stimulated by movement, electricity or stress.
- This material can be polymer, ceramic or quartz crystal.
- A change or shape in a material is a result of stress or movement applied producing an electrical signal.
- Commonly used in mobile phone speakers, gas lighters, quartz clocks and inkjet printers.
Litmus paper
Litmus paper
- Litmus paper changes colour when stimulated by a PH level.
- These strips of paper change colour when in contact with various levels of PH, turning red in acid and blue in alkaline.
- Commonly used for scientific experiments for PH levels, soil testing for gardeners and chemical balance for swimming pools.
