Development of a Novel Wearable Ring-Shaped Biosensor.

Area of Science:

• Biomedical Engineering
• Wearable Technology
• Physiological Monitoring

Background:

• The increasing demand for remote and continuous health monitoring necessitates advanced wearable solutions.
• Existing wearable sensors face challenges in accuracy and comprehensive physiological data acquisition.
• Integrating multiple sensors in a compact form factor is crucial for practical e-health services.

Purpose of the Study:

• To present preliminary results of a novel wearable module for healthcare services.
• To validate the accuracy of the module's Galvanic Skin Response (GSR) and Heart Rate Variability (HRV) sensors against a gold standard.
• To establish a foundation for a sensor-fusion system supporting active ageing, stress detection, and activity recognition.

Main Methods:

• Development of a wearable module integrated into a ring-shaped system.
• Inclusion of sensors for measuring Galvanic Skin Response (GSR) and Heart Rate Variability (HRV).
• Device validation through a study involving four subjects performing stress-inducing tasks, comparing module data with a commercial HRV-GSR sensor.

Main Results:

• The wearable module demonstrated high consistency with the gold standard commercial sensor.
• All measured GSR parameters showed agreement with the gold standard (differences < 10%).
• Two out of three measured HRV parameters also showed agreement with the gold standard (differences < 10%).

Conclusions:

• The preliminary results validate the wearable module's capability for accurate physiological measurements (GSR and HRV).
• This milestone supports the development of a sensor-fusion system for comprehensive e-health services.
• The ring-shaped wearable module shows potential for applications in active ageing, stress detection, and activity recognition.
