摘要

提出了一种基于聚乙烯醇-氧化石墨烯（PVA-GO）复合薄膜和聚二甲基硅氧烷（PDMS）薄膜的表面等离子体共振（SPR）传感器，用于同时测量相对湿度（RH）和温度。SPR效应是由涂覆Ag膜的MMF-SMF-MMF级联结构激发的，其中一个通道通过在其表面涂覆PVA-GO膜来激发，用于RH传感，另一个通道通过涂覆PDMS膜来激发，用于温度测量。实验结果表明，该传感器的相对湿度灵敏度为0.507 nm/% RH，温度灵敏度为−3.27 nm/°C。该传感器具有结构紧凑、成本低、稳定性好等优点，适用于农业储存、工业生产、天气预报等需要同时测量温度和相对湿度的领域。

Dual-Parameter Surface Plasmon Resonance Sensor for Simultaneous Detection of Humidity and Temperature Based on Cascaded PVA-GO Composite Film and PDMS Film

A surface plasmon resonance (SPR) sensor based on a polyvinyl alcohol-graphene oxide (PVA-GO) composite film and a polydimethylsiloxane (PDMS) film was proposed for simultaneous measurement of relative humidity (RH) and temperature. The SPR effect was excited by an MMF-SMF-MMF cascaded structure coated with Ag film, and one channel was excited by coating PVA-GO film on its surface for RH sensing, while the other channel was excited by coating PDMS film is used for temperature measurement. The experimental results show that the RH sensitivity of the sensor is 0.507 nm/% RH, and the temperature sensitivity is −3.27 nm/°C. The proposed sensor offers the advantages of compact structure, low cost, and stability and is suitable for fields that require simultaneous measurement of temperature and RH, such as agricultural storage, industrial production, and weather forecasting.
