Wearable multichannel-active pressurized pulse sensing platform.

Area of Science:

• Biomedical Engineering
• Traditional Chinese Medicine
• Wearable Technology

Background:

• Digitalizing traditional Chinese medicine (TCM) pulse diagnosis presents challenges due to limitations of current bulky or poorly integrated pulse detection devices.
• Existing technologies often fail to meet the practical application requirements for continuous and accurate pulse monitoring.

Purpose of the Study:

• To develop an innovative wearable active pressure three-channel pulse monitoring device for TCM pulse diagnosis.
• To enable accurate simulation of finger pressure for collecting pulse waves and predicting blood pressure status.

Main Methods:

• Integration of a flexible pressure sensor array, flexible airbag array, and active pressure control unit.
• Utilization of advanced machine learning algorithms and a mobile application for data analysis and human-computer interaction.
• High-sensitivity and high-linearity flexible pressure sensors (sensitivity: 460.1 kPa⁻¹, R² > 0.999) for precise pulse wave collection.

Main Results:

• The device accurately simulates finger pressure to collect pulse waves (Cun, Guan, Chi) at varying external pressures.
• Successful prediction of blood pressure status by analyzing pulse wave amplitude changes under different pressures.
• Demonstration of truly wearable, actively pressurized, continuous wireless dynamic monitoring of wrist pulse health.

Conclusions:

• The developed device offers a novel solution for digitizing TCM pulse diagnosis.
• The integrated platform provides a new paradigm for smart healthcare systems and continuous pulse health monitoring.
• The technology enables accurate and practical wearable pulse monitoring, advancing both TCM and digital health solutions.
