preparation example Construction

[0030] The preparation method of the sensor: first spin-coat a layer of polymer molecular brush material on the upper and lower substrates, and then self-assemble a layer of metal nanoparticles on the polymer molecular brush material, and then separate the two substrate materials at a certain distance The distance is relatively placed, the flexible transparent film material is wrapped around it, the transparent liquid is filled and sealed, and finally the gel material is spin-coated on the bottom to form a patch.

[0031] In the present invention, the external scattered light passes through the upper transparent film and irradiates the metal particles inside the sensor. As the temperature of the measured object changes, the state of the polymer molecular brush material changes, which further causes the distance between the two layers of metal nanoparticles connected to one end of the polymer molecule to change, making the position of the SPR peak of the metal nanoparticles chan...

Abstract

The invention proposes a metal-plasmon-patch-type temperature and infrared ray sensor. The surfaces between an upper layer flexible and transparent substrate and a lower layer flexible transparent substrate (5) are provided with a flexible polymer molecule brushing material layer (2) each. The outer end of each flexible polymer molecule brushing material layer (2) is connected with metal nanometer particles (3). The oppositely arrayed two layers of metal nanometer particles (3) and the flexible polymer molecule brushing material layers (2) form a unit structure. The unit structure can be a repetitive and multi-layered one. A flexible transparent film (1) is located around the above structure. Transparent liquid (4) is filled among the flexible polymer molecule brushing material layers (2) and the flexible transparent film (1). A patch (6) is arranged under the flexible transparent film (1) and is closely attached with the flexible transparent film (1). According to the invention, it is possible to directly observe with eyes or to use a camera to photograph the illuminating colors of the patch-type temperature sensor. Therefore, the sensor is suitable for objects with regular and irregular surfaces. With the sensor, a large area can be measured. Anti-electromagnetic interference can be realized. The responding is fast and the cost is low.

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 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 contact temperature sensors and non-contact temperature sensors. Traditional contact temperature sensors mainly include 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 te...
