The article proposes an enhanced surface plasmon resonance (SPR) temperature sensor using a gold (Au) film and liquid crystal (LC) film. The sensor's structure consists of a prism, Au film, and LC film, with the E7 LC film sandwiched between the BK7 glass substrate and the Au film. The study investigates the application of SPR phenomena in LCs for temperature monitoring, focusing on the resonance angle to detect temperature differences between 15 and 85 °C. The findings show that temperature variations cause significant fluctuations in the sensor's values, highlighting the sensitivity of different LC types. Simulations reveal slight differences in the resonance angles of various LCs, which poses a challenge for their use as accurate temperature sensors. However, the E7 LC shows promise as an efficient temperature sensor within the given temperature range, with the highest sensitivity measured at 0.249 deg/°C and the lowest at 0.002 deg/°C. The study concludes that SPR-based LCs, particularly the E7 LC, have the potential to be reliable temperature sensors in temperature-sensitive environments.The article proposes an enhanced surface plasmon resonance (SPR) temperature sensor using a gold (Au) film and liquid crystal (LC) film.
