Ways to Leverage Sensor Material Technologies

Case Studies

Thermochromic Technologies

 

Thermochromic products change color in response to temperature, with the two primary types being liquid crystals and leuco dyes. Liquid crystals are used in precision applications like thermometers, while leuco dyes are widely used in manufacturing, packaging, labeling, and permanent temperature-indicating inks for industrial quality control.

Thermochromic Inks/Dyes/Slurry

Thermochromic liquid crystals are reversible, temperature-sensitive materials that cycle through a full spectrum of colors as temperatures rise and return to black outside their active range. Available as ready-to-use 12” × 12” polyester sheets, they provide clear visual temperature indication for research, education, and non-destructive testing applications.
