Working With
Backed by UK research & innovation institutions
Reflex Lab is built on active clinical research collaborations and government-backed innovation funding — combining medical-grade validation with the resources to scale a new class of ANS biomarker.
Clinical Research
NHS Trusts
Active research collaborations validating Reflex HRV signals against clinical gold standards inreal care settings.
Innovation Funding
Innovate UK
UKRI-backed grant funding supporting Reflex's R&D in autonomic nervous system biomarker discovery and wearable validation.
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.
