In a breakthrough merging nature-inspired design with AI, an international team of researchers has developed a starfish-shaped wearable heart monitor that can accurately track multiple cardiovascular signals—even during intense physical activity.
Engineered by experts from the U.S., China, and Saudi Arabia, and detailed in Science Advances, the device captures electrocardiogram (ECG), seismocardiogram (SCG), and gyrocardiogram (GCG) data simultaneously. Unlike traditional wearable bioelectronics built on a single substrate, this pentaradial, five-arm structure minimizes mechanical interference, enhancing signal fidelity during real-life movement.
Key innovations include:
- AI-powered filtering of motion artifacts
- Bluetooth transmission to clinicians and mobile devices
- Edge computing for on-device analysis
- 91%+ accuracy in detecting conditions like atrial fibrillation, heart failure, and myocardial infarction
The waterproof, wirelessly charged device is also being optimized for mass production and daily use, though current adhesive materials may cause skin irritation. Researchers are now testing breathable, skin-friendly alternatives to improve comfort for long-term wear.
