Thermochromic fabrics utilizing cholesteric liquid crystal material

Abstract

A thermochromic fabric utilizing cholesteric liquid crystals includes a fabric material or garment formed therefrom. The liquid crystal material is patterned with a plurality of different liquid crystal formulations, whereby each formulation has high thermal sensitivity over a narrow temperature range. As a result, the aggregate pattern of liquid crystal material formed on the thermochromic fabric allows the thermochromic fabric to have high thermal sensitivity over a broad temperature range. As such, the fabric or garment may be worn on specific body parts of a patient, such as his or her feet, to assist in making a medical diagnosis.
