What are hydrochromic inks used for?

• Moisture testers

• Heat testers

• Colour testers

• Weight testers

What are thermochromic inks?

• They change colour in response to changes in temperature

• They change colour in response to changes in light

A modern material is...

• a material that has been recently developed for specific applications.
  
• a material that reacts to a stimulus
• a material invented since the year 2000
• a material with useful properties

These materials react and change with a physical change in their environment e.g. heat, light, electrical current.
