The IMPHYS Neurotelemetry System
A unified wearable platform that captures EEG, ECG, and SpO₂ simultaneously — processing every signal at the edge and transmitting synchronized multimodal data in real time.
Electroencephalography
32-channel dry-contact EEG captures broadband neural oscillations from delta through high-gamma. Spectral, connectivity, and ERP biomarkers are computed on-device by the STC and streamed to the host application.
Electrocardiography
Six precordial leads and four limb leads deliver clinical-grade cardiac monitoring. Heart rate variability, QRS morphology, and autonomic indices are fused with EEG streams to produce neurocardiac coupling metrics.
Pulse Oximetry
Ear-lobe reflectance oximetry provides continuous oxygen saturation and enables cerebral blood flow trend estimation. Low motion artifact at the ear lobe ensures clean baselines throughout extended cognitive assessments.
Biomarker Detection
On-device machine learning models detect fatigue, cognitive load, and autonomic stress in real time. Pre-trained on the NIHTB-CB normative dataset, models adapt to individual baselines within the first five minutes of a session.
Silicone NeuroTelemetry Headcap
The IMPHYS headcap is fabricated from medical-grade silicone with embedded dry-contact electrode discs positioned across the 10-20 international system. Its cable-free architecture eliminates the motion artifacts and impedance variability that plague traditional gel-based EEG systems.
An integrated Faraday mesh woven into the silicone substrate attenuates ambient electromagnetic interference by up to 42 dB, enabling high-fidelity neural recordings in unshielded clinical rooms, research labs, and field environments alike.
Compatible with standard 10-20 electrode placement protocols — no re-training required for clinical teams.
Streams to any phone, laptop, or tablet via Bluetooth 5.2 or Wi-Fi 6 — no proprietary receiver hardware required.
Signal Transmission Center (STC)
The STC is a suboccipital edge-computing hub that aggregates all sensor streams — EEG, ECG, and SpO₂ — into a single synchronized data pipeline. On-device DSP performs artifact rejection, spectral decomposition, and ERP averaging before transmission, reducing bandwidth requirements by 78% versus raw streaming.
A hardware timestamping engine aligns every neural, cardiac, and oxygenation sample to within ±1 ms, enabling single-trial event-related potential analysis and neurovascular coupling metrics that are impossible with asynchronous multi-device setups.
Faraday Shielding & Noise Rejection
Conventional EEG systems require electromagnetically shielded rooms costing upward of $200,000. The IMPHYS headcap's integrated Faraday mesh brings equivalent shielding to any environment — hospital ward, research lab, or remote field site — without infrastructure investment.
