Noninvasive Hydration Monitor for Challenging Environments

A noninvasive wearable sensor to accurately measure and inform the hydration of naval aviators in the flight environment is proposed. It uses multifrequency bio-electric impedance analysis to accurately measure skin hydration and Total Body Water content and provide feedback to the user in real time. The proposed wrist-worn band is self-contained, durable, suitable for an extreme range of environmental conditions, and integrates seamlessly with flight crew equipment. The proposed hydration monitor is also wireless, allowing hydration data to stream to any wireless sensor network. The solution is designed specifically for naval aviators but is ideal for DoD personnel, athletes, industrial workers, and consumers.
