Wearable Aircrew Hydration and Physiology Monitor

Physiological events are a recognized aviation hazard, so military aircrews are trained to recognize and respond to physiological symptoms. Of all causes of physiological events, one of the most treatable is dehydration, which can lead to fatigue, increased susceptibility to physical stressors, emotional alterations, and impaired judgment. Detecting dehydration early can reduce or eliminate this risk. Some consumer-oriented fitness trackers claim to monitor hydration, but they do not perform rigorous hydration measurements. Intelligent Optical Systems will develop a robust and wearable real-time hydration monitor, specifically designed for military aircrews. A novel luminescent microsensor will monitor electrolyte levels and skin biochemistry to accurately track hydration. This sensor platform will be compatible with other aircrew physiology monitoring sensors (for oxygen, carbon dioxide, lactate, stress biomarkers…). We will apply our expertise in sensor technology for detecting aircrew physiological events, and in medical sensing. In partnership with Lockheed Martin Aeronautics, and supported by the AFRL, we developed and validated through human subject studies a multi-parameter luminescence-based monitor for preventing hypoxia-like physiological events. In parallel projects we demonstrated luminescent sensors for continuously monitoring blood and tissue. Sensor materials and hardware developed in those projects will be the basis of the proposed military aircrew physiology monitor.
