liquid crystal

A substance that alters its color or changes from opaque to transparent when subjected to changes in temperature, electric current, pressure, or electromagnetic waves, or when impurities are present. Liquid crystals have been used to detect temperature fluctuation in infants and may be divided into two general classes: cholestric, which change color; and nematic, which can change back and forth from transparent to opaque.
