Abstract
Temperature and humidity sensors are applied in environmental monitoring, agriculture, the food industry, and biochemical detection. To enhance their sensitivity and efficiency, this work presents a temperature and humidity sensor that uses surface plasmon resonance (SPR) and photonic crystal fiber (PCF). The sensor comprises a hexagonal pattern of holes and two planes. On one side of the plane, a gold film coated with polydimethylsiloxane (PDMS) is used for temperature measurement, while on the other side, a gold film with polyvinyl alcohol (PVA) is used for humidity measurement. The finite element method is used to analyze the sensor’s sensing characteristics, revealing that its temperature sensitivity ranges from 20 to 90 ℃ at 3.82 nm/℃, while its humidity sensitivity ranges from 20 to 98% at 5.013 nm/%RH. Overall, this sensor can operate effectively in both temperature and humidity environments, simultaneously measuring both parameters.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
