Abstract

This thesis deals with the analysis on the fabrication of silica optical microfiber sensor coated with zinc oxide for sensing different uric acid concentration. The objective of this thesis is to fabricate, demonstrate and analyze the silica optical microfiber sensor coated with zinc oxide for sensing different uric acid concentration. The thesis describes the capabilities of optical microfiber in modern electronic bio-medical field for enhancement in uric acid detection system. Fiber optic, fiber optic sensor and uric acid characteristics were studied in this thesis. The optical microfiber sensor was varied based on the length of the tapering. The zinc oxide is used as the catalyst for the sensor to increase the sensitivity. The different uric acid concentration was analyzed by using the optical signal approaches. Finally, the different uric acid concentration were sensed by indicating the optical output power which then converted to voltage unit to determine the sensitivity. A graph of output voltage versus concentration of uric acid were plotted and it shows that the longer the tapered length, the higher the sensitivity of the sensor. Based on the results, it is observed that the analysis on the fabrication of optical microfiber sensor coated with zinc oxide for sensing different uric acid concentration yields more sensitivity and accuracy.
