SweatID makes it easy to pinpoint electrolyte levels and address dehydration issues before it happens. The SweatID patch is the first nonwoven fabric sensor to provide real-time hydration information by selectively targeting sodium levels on the skin, providing users with the data they need to accurately rehydrate during work, training, or competition. The disposable sensor is integrated into reusable clothing and sends data via Bluetooth to the connected app. The app categorizes the user’s sweat as having a low, medium, or high-sodium concentration and provides a personalized hydration strategy specifically tailored to their unique body chemistry.
