QUASAR’s dry, through-hair EEG sensors are the result of 25 years of innovation and over $35 million of R&D. Our proprietary system architecture eliminates motion artifacts and noise at the analog level—well before they ever reach your data-stream —ensuring unparalleled signal quality.
Our software delivers both raw and filtered data streams, and our expert team can develop custom algorithms to extract clear, actionable metrics tailored to your specific needs.
QUASAR’s sensors deliver high-fidelity EEG signal without compromising on convenience. Our Dry Sensor Interface (DSI) technology allows for quick and easy application—whether self-applied or assisted by a non-medical helper. No gels, no abrasion, no technicians—just seamless, high-quality EEG recording with zero hassle.
Comparison of EEG signals recorded using QUASAR (red) and wet (blue) electrodes simultaneously: Top) Alpha activity obtained by asking subject to close eyes. Bottom) Auditory Event-Related Potential (ERP) is generated by averaging EEG responses over 100 tone stimulations. EEG signals filtered between 1 Hz and 30 Hz.
QUASAR can integrate multiple physiological sensing modalities into a single, cohesive system in a form factor of your choice for detecting and diagnosing complex psychopysiological states. With years of experience in EEG, ECG, EMG, EOG, Pulse Oximetry, respiration, 6D inertial motion units and fNIR sensor integration, we provide a unified data stream—eliminating integration headaches and reducing sources of error in physiological monitoring and analysis.
QUASAR’s flagship dry electrode solution forms the basis of our work and powers our psychophysiological data acquisition systems. Our technology provides excellent signal quality in easy-to-use, comfortable, participant-friendly form factors that go from application to output in only minutes, without the use of gels or sticky pads. Our team is available to curate a system to your specifications.
