Development a polymer-based electronic pulse diagnosis instrument for measuring and analyzing pulse wave velocity

Area of Science:

• Biomedical Engineering
• Medical Devices
• Cardiovascular Diagnostics

Background:

• Pulse wave velocity (PWV) is a key indicator for cardiovascular health.
• Conventional pulse diagnosis instruments are often rigid and lack flexibility.
• There is a need for advanced, flexible systems for precise PWV measurement.

Purpose of the Study:

• To propose and evaluate a novel, flexible pulse-diagnosis system for measuring pulse wave velocities.
• To demonstrate the system's feasibility in applications related to cardiovascular diseases.
• To assess the performance of the developed system through sample measurements.

Main Methods:

• Utilized a conductive elastic polymer as the sensor material for flexibility.
• Integrated a flexible sensor with a wrist-type pulse-wave acquisition system.
• Employed the LabVIEW platform for signal processing and pulse waveform reconstruction from cun, guan, and chi signals.

Main Results:

• Successfully fabricated a flexible pulse diagnosis instrument with enhanced formability.
• Demonstrated stable measurements through integration with a contemporary wrist-type system.
• Analyzed 20 measured samples to evaluate system performance and feasibility.

Conclusions:

• The novel flexible pulse diagnosis system shows promise for accurate PWV measurement.
• The system's design facilitates stable and reliable data acquisition.
• This technology offers a feasible approach for cardiovascular disease risk assessment.
