Pulse Clinic · clinical-grade tier

The chest-worn sensor
for high-risk children.

Pulse Clinic is the clinical-grade hardware tier of Pulse. A chest-worn sensor monitors a child's breathing pattern, accelerometer movement and on-device PM2.5 continuously, and predicts respiratory exacerbations 6–24 hours ahead. Designed for the paediatric burn-season cohort in Northern Thailand, deployable in any high-PM population worldwide.

Two tiers, one signing stack

Pulse Clinic (this page)

In pilot Q3 2026

Chest-worn sensor for prescribed clinical use. Continuous monitoring, 6–24h prediction window. Same Ed25519 envelope as the phone app, signed on-device by an ATECC608B secure element. EU MDR Class IIa pathway.

What's inside the device

  • ESP32 microcontroller with low-power radio for sync to the parent's phone
  • Pulse-oximeter sensor for SpO2 and heart-rate variability
  • 3-axis accelerometer for chest-wall movement and breathing-pattern detection
  • On-device PM2.5 sensor for the child's actual exposure (not just ambient regional readings)
  • ATECC608B secure element signs every reading on-device with Ed25519; no key ever leaves the chip
  • Bill of materials under €30. Engineered for deployability in low-income and high-exposure settings, not for premium-pricing optics

Why it lives next to the phone app

The Pulse phone app on-boards parents and produces baseline data for every child who uses it — ambient air quality at home, daily self-check, longitudinal Signature. When the clinic identifies a high-risk child during the pilot, Pulse Clinic is the prescribed upgrade. Both tiers sign every record with the same primitives, so a clinical auditor verifies records from the parent's phone and the child's chest sensor with one public key.

Self → clinic. The pattern Apple Watch normalised for cardiology, applied to paediatric respiratory in the burn-season corridors no incumbent wearable serves.

Regulatory posture

  • EU MDR Class IIa software-as-medical-device pathway. Technical file drafted; clinical evaluation begins with the Q3 2026 pilot.
  • EU AI Act Annex III §3 (medical device safety) — high-risk AI obligations designed in from day one.
  • ISO/IEC 42001 AI management system aligned with the sibling AqtaBio product.
  • GDPR Article 9 health-data processing under contract with the prescribing clinic; no Aqta cloud in the trust path.

The pilot

Clinical pilot Q3 2026 at Uttaradit Hospital paediatric clinic, Northern Thailand. Clinical lead: Dr Panurat Kanjanapradit, paediatrician and lecturer (family relationship to Aqta founder disclosed; pilot under independent evaluation criteria with quarterly outcome reporting). Target cohort: paediatric asthma during the May–July burn-season exposure window.
