The cholesteric liquid crystals, which, depending on the concentration at different temperature, assume a different color, are responsible for the measurement of temperature. LCs are reversible in that they can be used over and over again. This change in molecular structure affects the wavelengths of light that are absorbed and reflected by the liquid crystals, resulting in an apparent change in the color of each temperature event. LCs are very similar to the liquid crystal displays used in watches and laptop computers, but our thermochromic LCs change color with temperature instead of voltage.
