The Challenge: Three Technical Hurdles to 24/7 Monitoring
The promise of earlier disease detection through continuous monitoring is slowed by three key technical hurdles that separate consumer gadgets from clinical-grade medical devices.
Skin Interface & Adhesion
Electrodes must maintain strong signal contact for 7+ days through sweat, showering, and exercise without causing skin irritation.
Motion-Artefact Suppression
Real-time adaptive filtering is needed to remove noise from arm swings and muscle contractions that corrupt sensitive biosignals.
Medical-Grade Validation
Algorithms must be validated to meet stringent accuracy standards across diverse global populations (skin tones, BMI, etc.).
Key Outcomes: Ranked Solutions for a Medical-Grade Wearable
Our analysis identified and ranked five complete sensor-stack solutions that met the client's targets for signal accuracy, wear duration, and BOM cost.
| Rank | Solution Highlights | Key Performance Indicator (BP Error) | BOM Cost |
|---|---|---|---|
| 1 | ZnO nanowire dry ECG + triple-LED PPG + piezo tonometer on stretch TPU | ±4.8 mmHg | €16 |
| 2 | Graphene dry electrodes + dual-site PPG (wrist + finger ring) with sensor fusion | ±5.2 mmHg | €17 |
| 3 | Micro-fluidic pressure patch (tonometry) + optical SpO₂ | ±3.9 mmHg |
