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.

Abstract translation: 使用胆甾型液晶的热变色织物包括由其形成的织物材料或衣服。 液晶材料用多种不同的液晶配方构图，由此每种配方在窄的温度范围内具有高热敏感性。 结果，形成在热变色织物上的液晶材料的聚集体图案使得热变色织物在宽的温度范围内具有高的热敏感性。 因此，织物或衣服可以佩戴在患者的特定身体部位，例如他或她的脚，以协助进行医学诊断。
