A Metal Plasmon Patch Type Luminous Temperature and Infrared Sensor

Abstract

The present invention is a metal plasmon patch type luminous temperature and infrared sensor device. There is a layer of metal nanoparticles (4) on a flexible transparent substrate (6), and a luminescent substance (5) with a core-shell structure is located on the metal nanoparticles. Around, the polymer molecular layer (3) is located above the metal nanoparticles, and its bottom end is connected to the substrate or metal nanoparticles. The unit structure composed of metal nanoparticles, polymer molecules, and luminescent substances can be repeated for multiple layers, and the flexible transparent film ( 1) Located around the above structure, the transparent liquid (2) is filled between the polymer molecules and the flexible transparent film, and the patch (7) is located under the underlying flexible transparent film and clings to the film. The sensor is attached to the surface of the measured object through the gel patch at the bottom of the sensor, and the upper surface of the patch is directly irradiated with an ultraviolet lamp. The luminous color of the patch temperature sensor can be directly observed by human eyes or photographed by a camera, and is suitable for objects with regular and irregular surfaces.

Description

technical field [0001] The invention belongs to the field of temperature and infrared sensors, and in particular relates to a metal plasmon patch type luminous temperature and infrared sensor, in particular to a flexible and luminescent patch temperature and infrared sensor. Background technique [0002] The current temperature sensors mainly include traditional temperature sensors, including thermistors and thermocouples. The thermistor utilizes its own resistance-temperature characteristics, the temperature changes, and the resistance value also changes, but its self-heating phenomenon seriously affects its temperature measurement accuracy. Thermocouples use the thermoelectric effect to convert the temperature difference between the two ends of the couple into an electromotive force difference, but their sensitivity is low and their stability is poor. At high temperatures, the nonlinearity of their own temperature characteristics is very obvious, which limits their tempera...
