At QUASAR, we engineer advanced multimodal systems that combine dry electrode technology with EEG, fNIRS, ECG, and other biosensors to capture high-fidelity psychophysiological data—without compromising comfort or usability.
Our precision sensing solutions are designed to quantify and optimize human cognitive and physical performance, even in the most challenging environments. By integrating new sensor montages into custom form factors and adding real-time data interpretation, we empower users to gain deeper insights into complex mental and physiological states.
QUASAR has over two decades of experience in the development of wearable devices and algorithms for cognitive state assessment. Our multimodal sensor platforms are paired with proprietary algorithms that interpret complex physiological signals into meaningful, actionable insights—enabling real-time classification of cognitive states with accuracies exceeding 90%.
To support the Department of Defense’s need for real-time monitoring of warfighter readiness, QUASAR has developed advanced sensing systems tailored for aviators in operational environments. These needs include continuous, unobtrusive measurement of cognitive workload, fatigue, and physiological strain to enhance mission performance and safety.
Our solutions, including the Dry Electrode Flight helmet Integrated EEG System (DEFIES), ECG EOG Electric Stimulator (GOES), and Cognitive Health and Physiological Sensors (CHIPS), are designed to operate seamlessly in or under military flight helmets. They capture EEG, ECG, and related biosignals during live flight operations, giving researchers and mission planners a clear, real-time understanding of pilot psychophysiological state. This enables better decision support, training optimization, and risk mitigation in dynamic operational environments.
QUASAR’s DEFIES system integrates our uniquely high sensitivity and low noise dry electrode EEG sensors into the HGU-68/P flight helmet.
CHIPS integrates nonintrusive functional Near InfraRed Spectroscopy (fNIRS) and Ballistic Impact Detection (BID) sensors into a flight helmet. The fNIR sensors conduct Operator State Monitoring (OSM) of physiological factors while the BID sensors detect hydrostatic shock resulting from ballistic impacts.
Our lightweight, low-profile EOG headband is optimized for continuous fatigue and sleep monitoring in demanding operational environments.
Combined with QUASAR’s proprietary fatigue detection algorithms and vagus nerve stimulation capabilities, GOES enables real-time fatigue assessment and mitigation. Its sleek, wearable design makes it ideal for sleep research, field-deployable monitoring, and enhancing recovery and operational readiness in warfighters.
QUASAR has developed novel ballistic impact detection sensors capable of detecting pressure waves from gunshots or explosive blasts. These sensors can operate independently to provide binary impact alerts or be deployed in an array to localize the point of impact on the body with precision.
QUASAR’s dry ECG electrodes enable measurements even when subjects are moving and sweating, making them ideal for athletic performance monitoring. Our systems provide full ECG, not just heart rate, and can be incorporated into belts, shirts and even chairs. For applications where direct skin contact is infeasible, our capacitive ECG sensors can provide full-morphology ECG through a single layer of fabric such as a T-shirt.
QUASAR’s inherently water-resistant electrodes feature in a multi-modal system developed for the US Navy that provides research-grade ECG, respiration, skin temperature, and activity data and can be worn under a standard wetsuit. The system was validated in a saltwater pool at the
Scripps Institution of Oceanography to a depth of 10 meters. More information is available about the project here.
