Abstract

This research describes the development of an effective optical microfiber sensor for glucose detection. The objective of this project is to study the operation and performance of a glucose sensor using optical microfiber technology, to develop the glucose sensor and test its sensitivity and performance in various glucose concentration tests, and finally, to analyze the performance of the glucose sensor in different environments and experimental conditions. For this project, the optical microfiber was successfully fabricated with a different wavelengths (1310 nm and 1550 nm) were used for testing The key findings of this project are the sensitivity and linearity of the sensor, determined by comparing the gradient values and R² based on the graph obtained from OTDR (Optical Time-Domain Reflectometer) measurements. By analyzing the comparison results, the ideal wavelength for glucose sensing can be determined. Hence, the study successfully fulfills its objectives.
