thermochromic

The URI researchers began studying thermochromic pigments – those that change color at certain temperatures -- a decade ago when a cookware company sought a polymer that could be added to its products to make them change color when they were too hot to touch.

Depending on the type of external stimuli applied to bring about the reversible color change, the chromogenic materials are further subclassified as photochromic (light activated), electrochromic (electric field activated), thermochromic (heat activated), gasochromic (gas exposure activated), piezochromic (pressure activated), magnetochromic (magnetic field activated) and more [1].
