Durable Textile-based Sensor for Repetitive Glucose Measurement

Abstract

Diabetes is one of a disease with high growth in this world. At the end of 2030, the World Health Organization predicts that the number of cases of diabetes worldwide will exceed 500 million, considering this condition preventive and corrective action are needed through simultaneous measurement of blood sugar levels. A new method has been developed that allows the blood sugar checking levels to be carried out continuously to achieve a comprehensive assessment non-invasive. This research studied the process of designing and fabricating a single-layer textile-based sensor through the direct coating method. The sensor's capabilities were assessed using a glucose solution with concentrations ranging from 10 to 50 mM at a voltage of 0.55 V for 300 seconds with a time interval of 0.5 seconds. Subsequently, durability testing of the sensor against repeated folding was conducted by subjecting it to repeated 90° folds with intensity variations of 0 to 50 times before chronoamperometry measurements were executed. It is observed that the design and fabrication of conventional single-layer textile-based sensors can be achieved using the coating method with carbon paste and Ag/AgCl paste on double-faced fabric. The single-layer textile-based sensor in this research demonstrates superior durability compared to screen-printed carbon electrode sensors.
