1. A composite sensor fibre comprising a filamentary core and an outer layer encapsulating an intermediate sensor layer of a flowable and detectably thermochromic liquid crystalline material between the filamentary core and the outer layer, the thermochromic liquid crystalline material comprising at least one selected from cholesteryl oleyl carbonate, cholesteryl nonanoate, cholesteryl 2, 4-dichlorobenzoate, cholesteryl benzoate, cholesteryl propionate, cholesteryl oleate, and cholesteryl chloride, wherein the outer layer is transparent and the filamentary core is configured to provide a contrast for facilitating the observation of temperature or temperature gradient changes in the thermochromic liquid crystalline material, and wherein the temperature or temperature gradient changes comprise changes in color or color gradient.
