The available health monitors assist athletes for the physical monitoring training. While athletes train, the increase in muscular metabolic rate produces Lactic acid as a metabolic byproduct causing muscle cramps. To release muscle cramps sodium and potassium salt supplements are prescribed in higher dosage to athletes. The purpose of this study is to develop a system WIRELESS SWEAT SIGNAL ANALYSER for athletes, to provide athletes with adequate dehydration warning by sweat analysis. The sweat analyzer developed can aid in monitoring diseases related to salt deficiencies such as Goitre, Cretinism, Hyponatremia, Cystic Fibrosis etc. Though there are saliva and urine salt sensor, their accuracies are not appropriate for estimation of continuous dehydration levels, so sweat analysis comes as a viable solution for analyzing. The system proposed will use sweat as the biofluid along with low power components and the data can be wirelessly transmitted to the registered Smartphone, for further interpretations on dehydration analysis and provide adequate warning to the nearby mobile units and the athlete for salt supplementation.
