Gateway Engineering Coalition Home Page    Liquid Crystal Thermometry

Liquid crystals possess the mechanical properties of a liquid, but have the optical properties of a single crystal. Temperature changes can affect the color of a liquid crystal, which makes them useful for temperature measurement. The resolution of liquid crystal sensors is in the 0.1 C range. Disposable liquid crystal thermometers have been developed for home and medical use.
