Glucose Detection in Sweat using Biosensors

Physical activity and physical fitness may lead to extended health benefits. The human body loses lots of electrolytes during physical activity through perspiration and there is a need to replace them with special drinks, thus we introduce a smart wearable sensor that allows sweat monitoring using biosensors providing realtime feedback through a smartphone application informing the user when there is need to replace electrolytes. The system is based on a potentiostat with wireless communication capabilities that performs electrochemical analysis using biosensors. The preliminary results were obtained using commercial glucose sensors and compared with a glucose meter. A glucose solution was prepared with different concentrations tested using chronoamperometry. The system proved to be efficient in the measurement of high and low concentration of glucose in sweat.
