Real-time Non-Invasive Monitoring of C21SR Cognitive Performance Using Off-Body Sensors

This program combines state-of-the-art (SoA) expertise in the relationship between physiologic variables and cognitive performance with pioneering knowledge in the development of high- impedance bioelectrodes. The recent development of these new electrodes enables accurate measurement of bioelectric signals without contact to the skin, and opens up the possibility of a wearable sensor suite for operational environments. The goal of Phase I is to relate the number and placement of electrodes and their required fidelity with accuracy in monitoring performance. The study will be done using existing EEG and heart rate data collected by conventional wet electrodes on subjects performing mentally challenging tasks and undergoing physical and mental stress during military training exercises. To augment these, the benefit of adding a near infrared measurement of oxygen usage in the brain will be assessed via SoA physiologic models. The result will either be a clear argument that these core sensors are sufficient or a case for additional sensors. In Phase II, a prototype sensor array and algorithms for assessment of C2ISR operator performance will be demonstrated. The target configuration is a noninvasive array of the new bioelectrodes and infrared sensors mounted on the inside of a helmet with in-clothing ECG sensors.
