A portable wireless spirometer device for long-term pulmonary function monitoring and training

Area of Science:

• Biomedical Engineering
• Respiratory Physiology
• Wearable Technology

Background:

• Traditional spirometers have limitations for daily and long-term respiratory monitoring.
• Portable wireless solutions are needed for accessible pulmonary function assessment.
• Effective breathing training requires accurate and real-time feedback.

Purpose of the Study:

• To introduce a compact, lightweight, wireless respiration sensing device.
• To enable real-time feedback for pulmonary function assessment and breathing training.
• To validate the device's performance in distinguishing expiratory characteristics and tracking recovery.

Main Methods:

• Theoretical deformation calculations to determine airflow sensor parameters.
• Optimized airway design to enhance airflow acceleration and sensor sensitivity.
• Development of a cross-platform interactive graphical interface for data visualization and training.

Main Results:

• The device achieved a ~10.4-fold increase in airflow acceleration at the sensor.
• Successfully distinguished expiratory characteristics of six volunteers.
• Effectively tracked respiratory recovery post-high-intensity exercise.
• Integrated into engaging games for consistent breathing training.

Conclusions:

• The portable wireless respiration sensor is a viable tool for pulmonary function monitoring and training.
• The device's design enhances sensitivity and accuracy for real-world applications.
• Interactive features and gamification promote user adherence to breathing exercises.
