利用热敏液体作为中间体并结合光纤SPR结构，提出了一种用于温度检测的光纤表面等离子体共振(SPR)传感器。该传感器的传感元件是通过将涂有银层的光纤探针封装到充满热敏无水乙醇的毛细管中而制成的。这种封装可以保护金属层不被氧化和损坏。此外，根据对比实验，该传感器的灵敏度达到了1.5745 nm/℃，远高于传统光纤SPR传感器。
A fiber-optic surface plasmon resonance (SPR) sensor for temperature detection has been proposed by utilizing a thermosensitive liquid as the intermediate and combining with the fiber SPR structure. The sensing element of the sensor has been fabricated by packaging the fiber probe coated with a silver layer into a capillary filled with thermosensitive anhydrous ethanol. This packaging can protect the metal layer from oxidation and damage. Moreover, this proposed sensor achieves a sensitivity of 1.5745 nm/degrees C, which is much higher than that of the traditional fiber SPR sensor according to the comparative experiments.
