| Summary: | This research discussed on developing a glucose sensor with real time calibration. In general cases, the blood sugar level is checked through puncturing the fingertip to get the blood sample on a test strip. Moreover, this method is not convenient for the patients because it requires changing of the
strips for taking the blood samples every time and its price is also higher. This may expose the patients to infections while taking the blood samples. A non-invasive method is developed in this work to improve the old method. A near infrared (NIR) sensor is used to detect the scattering and absorption of light through glucose concentration. The simulation and construction of
glucose sensor circuit are implemented through testing different solutions of glucose concentration (50-300 mg/dL) using microcontroller and Matlab software. The data of blood tests from 6 patients are compared and analyzed with the constructed glucose sensor. Results show that, the glucose sensor can detect the glucose concentrations (hyperglycemia, normal and hypoglycemia level) through finger and display it on Liquid Crystal Display (LCD). This sensor is able to provide an alert if glucose level reach higher than normal range. So the diabetes disease can be monitored in real time without difficulties of the patients in addition this method is competitive, affordable and
convenient for the patients. |
