There is no shortage of fitness-tracking wearables that tell you when you need to get moving, but soon a device that acts as a hydration tracker could be available. Staying hydrated is extremely important to your health, and drinking more water acts as a cure to many ailments from headaches to clear skin. Researchers at North Carolina State University are developing a tiny hydration-tracking wearable that would tell you when you need a drink.
The gadget is described in a scholarly paper called 'A Wearable Hydration Sensor with Conformal Nanowire Electrodes' by Alper Bozkurt, Feiyan Lin, Abhishek Malhotra, John F Muth, Amanda Myers, Shanshan Yao and Yong Zhu. The hydration tracker is a bluetooth sensor that monitors hydration of the skin.
