CSA · Bio-Monitor

Bio-Monitor combines a smart shirt, headband and tablet to record pulse/ECG, blood pressure, breathing, skin temperature, oxygen saturation and activity on the ISS.

This is an existing CSA system, not evidence that Nabd has implemented or validated those measurements.

NASA · Wearable biosensor evaluation

Astroskin testing in HERA assessed signal quality, crew usability and comfort before considering future spaceflight use. An analog technology demonstration does not validate Nabd hardware, thresholds or clinical performance.

CSA · Space Health study

The Space Health study uses Bio-Monitor data and the Artemis AI platform to investigate cardiovascular adaptation in spaceflight. Research use of AI is not evidence that this assistant can diagnose or predict an individual health outcome.

NASA · Sleep, circadian rhythm & workload risk

NASA identifies sleep loss, circadian desynchronization and work overload as risks for performance decrements and adverse health outcomes. This risk framework does not validate Nabd sleep estimates, scores or individual thresholds.

NASA · Behavioral health evidence report (2025)

NASA reviews cognitive, behavioral and psychiatric risks for in-mission health, performance and long-term outcomes. A mood score or chat response is not a psychiatric assessment. Persistent distress requires human support.

NASA · Five spaceflight hazards

Radiation, isolation/confinement, distance from Earth, gravity fields and closed environments frame human spaceflight risks. Hazard descriptions provide context, not clinical validation of Nabd rules or the conceptual circuit.

Evidence is not validation

All thresholds, scores, simulated doses and forecasts in this demonstration are illustrative. Repeated readings, symptoms and professional assessment remain essential. The activity index is not a bone-density measurement. Camera simulation is not a validated sensor.
