MomSafe AI：可穿戴硬件与预测 AI 构建孕期连续监护系统

The Problem: Traditional prenatal care is episodic. A 15-minute checkup once every four weeks leaves expectant mothers unmonitored for over 95% of their pregnancy—the exact window where complications like preeclampsia, gestational hypertension, and cardiac distress develop silently.

Our Solution: MomSafe AI builds the missing continuous bridge. Pairing an ergonomic, medical-grade physiological wristband with our cloud intelligence layer, MomSafe AI synthesizes continuous biometrics into real-time, explainable guidance for mothers and obstetric care teams.

⌚ 1. MomSafe Band™ (Custom Wearable Hardware)

Ergonomic Smartband: Designed from the ground up for 24/7 continuous wear, featuring a lightweight profile and skin-safe medical-grade silicone strap.
Custom Miniaturized PCB: High-density multi-layer board integrating an ultra-low-power dual-core processor, BLE 5.0 wireless telemetry, and power management.
Advanced Biosensing: Multi-wavelength optical photoplethysmography (PPG) for continuous heart rate, blood oxygenation ($\text{SpO}_2$), and HRV tracking.
Dedicated Thermal Barrier Isolation: Proprietary mechanical thermal design separating internal processor heat from skin-contact temperature sensing to ensure clinical baseline fidelity.
Motion & Gait Intelligence: 6-axis inertial measurement unit (IMU) contextualizing biometrics during rest, sleep, and physical activity.

📊 2. Clinical Command Center (Dashboard & Web App)

Live Vital Stream: Real-time visualization of heart rate, oxygen levels, basal temperature, and blood pressure trends.
Trimester-Adaptive Safe Zones: Automatically shifts physiological reference baselines across Trimester 1, 2, and 3.
Nutrition & Macro Tracking: Caloric targets, elemental iron, calcium, and folic acid logging specifically tailored for fetal development.
Symptom & Kick Counter: Daily logging of fetal movement velocity, hydration volume, sleep quality, and emotional wellbeing.

🧠 3. Maternal Risk Index (MRI)™ (Clinical AI Engine)

Multi-Factor Anomaly Scoring: Synthesizes multi-parametric biosignals into a clear, unified risk tier (Optimal, Advisory, Elevated, Critical).
Synergy Detection: Detects correlated physiological anomalies—such as concurrent blood pressure elevation and heart rate acceleration.
Zero-Hallucination Directives: Uses deterministic, evidence-based clinical rules rather than unconstrained generative text, ensuring consistent and safe guidance.
Explainable "Do This Now" Cards: Delivers immediate, stress-reducing, practical instructions whenever metrics require attention.

📍 4. Emergency Hospital Radar (Geospatial Safety)

Accredited Facility Locator: Interactive Leaflet / OpenStreetMap discovery of nearby hospitals equipped with 24/7 obstetrics and neonatal intensive care units (NICU).

🛡️ Security, Privacy & Compliance Posture

Maternal health information requires the highest standard of data guardianship. MomSafe AI enforces a zero-trust security model:

Row Level Security (RLS): Enforces strict cryptographic tenant isolation in PostgreSQL, ensuring user records can never be cross-queried.
End-to-End Encryption: All wearable and gateway telemetry flows over TLS 1.3 encrypted pipelines with device-scoped authentication tokens.
Privacy-First AI: The Maternal Risk Index (MRI)™ executes within secure application boundaries—biometric health telemetry is never sold or passed to third-party commercial LLMs.
