Abstract: A thin film thermometer has multiple temperature sensors that individually appear within certain concealing features of the decal under different temperature ranges, otherwise blending into the concealing features and thereby disappearing into the design. Among other uses, this thermometer may be implemented as an adhesive bandage or refrigerator magnet, and may include special features such as a hologram, heat blocking backing, and ink-preserving adhesive tie coat. Also, enhanced visual effects are achieved through the coordinated multiple activation of temperature sensors.
