A liquid crystal device (10) includes at least two layers of encapsulated thermochromic, e.g., liquid crystal, material (14, 16) for providing a color response with respect to temperature, the temperature ranges of color response of the at least two liquid crystal layers being different, a mechanism (18) for distinguishing the temperature range in which the device is operational, and a support (20) for supporting the at least two liquid crystal layers and distinguishing mechanism for positioning with respect to at least part of a body. A method for making the liquid crystal device and a method for using the liquid crystal device to detect and to indicate the temperature of a body. |
