Study on sweat glucose analysis method based on photoelectric colorimetry

Diabetes, as one of the primary diseases threatening human life safety, has seen its traditional home blood glucose testing method involving finger pricking cause discomfort to patients. Therefore, there is an urgent need for a non-invasive, efficient, and simple home blood glucose testing method. Since sweat glucose concentration correlates with blood glucose concentration and sweat is easily accessible, this paper proposes a method for analyzing sweat glucose based on photoelectric colorimetry. The developed "mosquito coil-shaped" active sweat-absorbing microfluidic patch is used to collect sweat, which is then analyzed for glucose concentration using a colorimetric test strip. The produced colorimetric test strip works well in conjunction with the photoelectric colorimetric sensor, where the R color component shows a high linear correlation with glucose concentration, enabling precise detection of changes in glucose solution concentration. This patch can effectively collect human sweat samples and accurately analyze the glucose concentration within them, providing practical reference data for home self-testing by diabetic patients. It aids in monitoring blood sugar fluctuations, enhancing self-management capabilities and disease control efficacy, and holds promise for advancing diabetes management technology
