Abstract
A thermochromic element including a thermochromic layer including a binder and a thermochromic pigment chosen to react at a specific temperature so that the pigment passes from a first color to a second color when the specific temperature is reached. The thermochromic layer coats a thermally conductive layer, and is protected by an optically transparent layer that protects it from chemical and physical degradation.
