What is thermochromic?
Changes colour in response to temperature
What is phosphorescent?
Absorbers light energy during the day and re-emits the light energy when it’s dark
What is photochromic?
Changes colour with light intensity
What is piezoelectric?
Gives of a small electrical charge when deformed
What is electroluminescent?
Thin copper wire coated in a phosphorescent material which glows in response to an alternating current
What is a shape memory alloy
Changes shape in response to a change in temperature or electrical input
