Detection of glucose concentration in distilled water with volumes of 70 μl has been successfully demonstrated. The working principle of the sensor is based on displacement sensor using fiber coupler and concave mirrors as reflector which also acts as sample container. The glucose concentration is detected through peak voltage value due to the shift of the sensing port fiber coupler against the concave mirror. Peak voltage value will change depends on glucose concentration. The developed sensor can detect changes in glucose concentration with a range of 0-50% and 1% resolution without contact with the sample.
