Study of Fiber Optic Sensor for Various Biomedical Applications

Fiber optic sensors have been widely used in various biomedical applications due to their high sensitivity, reliability, and non-invasiveness. In this paper, we propose a novel approach to designing an optical sensor for detecting impurities in a mixture. The proposed sensor utilizes a flexible polymer layer and an optical fiber cable to detect variations in the power of the adulterated mixture. The polymer layer is made of PDMS, which swells or shrinks in response to the level of adulteration present in the mixture. As a result, the intensity of the output spectra changes, which can be used to detect impurities. The sensor's results will be compared with those obtained from the pure mixture to evaluate its accuracy. In conclusion, the proposed sensor has several advantages, such as low cost, easy to handle, ease of fabrication, and high sensitivity, making it a promising candidate for detecting impurities in various mixtures.
