ABSTRACT:
A method of determining temperature and temperature distribution over the surface of an object includes (a) applying a temperature sensitive film composed of material displaying change in color as a function of temperature on a surface of an object; and (b) comparing the color changes on the film with predetermined color and temperature data developed for the film. A related temperature indication device includes a temperature indication device for measuring the temperature and temperature distribution over a surface of an object comprising: a thin film composed of a plurality of fibers embedded in an inert binder wherein the plurality of metal or metal alloy fibers have a property whereby the fibers exhibit color change as a function of temperature, when the thin film is engaged with the surface of the object.
