Data Pipeline
From wrist to query
REFLEX wearables capture raw RR intervals at medical grade. The data flows into the Bio Data Bank and is exposed via a governed query layer — with full audit trails and on-chain attribution.
01 — Capture
Wearable Capture
Raw RR intervals via BLE from RFLXR&D devices, sampled continuously during sessions.
02 — Store
Bio Data Bank
Anonymised, indexed recordings with consent flags and governance metadata attached.
03 — Query
Labs Query Layer
Researchers query via the Reflex Lab interface with usage-based billing and full attribution.
Available Signals
40+ ANS features ready to query
Every Reflex recording is processed to extract time-domain, frequency-domain, and non-linear HRV features — available to all approved researchers.

Evidence · Method comparison
Measured against clinical references
Before a metric earns a place in Reflex, it's checked against an established reference — Vive ring-derived inter-beat intervals against a Polar H10 chest-strap ECG, the gold standard for R–R timing. Every point below falls inside the ±5 bpm corridor used as the industry tolerance.
