Facile and Low-Cost Sensor System for Exploration of Non-Invasive Glucose Measurement

Abstract

Among all other disease, diabetes is also one of the major health problems causing nearly 4.5 million deaths per year. According to the international diabetes federation 463 million people were suffering from the diabetes in 2019. It is estimated that this number will raise to 700 million by the year 2045. As, there is no cure for this disease even though level of glucose in the blood should be monitor inflexibly to get rid of more complications. So, monitoring of glucose level in the blood become inexorable need leading the researchers to manufacture a human friendly device which can accurately measure the blood glucose level. Conventionally invasive method is used worldwide to measure the blood glucose level from the blood sample. In this research work facile, low cost glucose characterization sensor is reported for the exploration of non-invasive glucose monitoring using biofluids. In this research work characterization of glucose concentrations from (1mM – 5mM) is performed successfully using facile, low cost glucose sensor. Platinum coated material is used for the sensor electrodes to minimize the cost of the sensor. Platinum based chronoamperometric glucose (PCAG) sensor is proposed in this research work. FR-4 substrate is used for the PCAG sensor. Low cost Portable potentiostat is fabricated to maintain potential across PCAG sensor electrodes. Characterization is performed for aqueous glucose solutions along with the glucose solutions in presence of impurities.
