Abstract

According to the USAF Scientific Advisory Board's New World Vistas report, EEG measures of brain activity will be critical to 21st century Air Force operations, helping to optimize overall human-system performance, accelerating personnel selection and training, and improving workload and fatigue monitoring. Current EEG sensors are ill-suited for use in operational settings, requiring manual preparation of the skin surface prior to application, and the use of messy liquid or gelatinous electrolytes. We are developing an instant application sensor that will overcome these problems. In Phase I we designed a prototype Rapid Application Cutaneous Electrode (RACE). This comfortable sensor is applied without prior scalp preparation, yields reliable EEG recordings over long periods, and leaves minimal residue on the scalp. We also designed a prototype rapid application headset. In Phase II we will further develop and test the RACE, implement it in a rapid application headset, modify it for use in flight helmets, and integrate it with a wireless miniaturized digital EEG data acquisition system. The resulting system will permit simultaneous monitoring of brain activity from whole flight crews or other workgroups, a capability currently only possible under highly contrived circumstances.
