To visualize the idea of our work a simple movie has been presented. This movie shows the principle of how it is possible to control the color of thermochromic strips while changing external temperature. The presented experimental device consists of three elements: radiator, Peltier’s device and a black thermochromic strip as an example. When the temperature goes up the characteristic black color of strip disappears (at about 20°C). This effect is fully reversible as demonstrated in the movie. The speed of changes depends on the value of applied current, while the direction of changes depends on polarity of current.

In our paper we constructed CVD-graphene based flexible, thermochromic sensor where instead of Peltier device CVD-graphene layer was used.
