Area of Science:

• Biomedical Engineering
• Respiratory Medicine
• Signal Processing

Background:

• Non-invasive respiration detection is crucial for healthcare and disease diagnosis.
• Minimizing patient burden and enabling real-time monitoring are key advantages.
• Identifying abnormal breathing patterns is essential for diagnosing respiratory disorders.

Purpose of the Study:

• To present a non-invasive C-band sensing technique for detecting multiple breathing patterns and respiratory rates.
• To evaluate the feasibility of this non-contact method for measuring various breathing patterns.
• To detect abnormal breathing patterns in real-time using C-band sensing for potential respiratory disorder diagnosis.

Main Methods:

• Utilizing a C-band sensing technique for non-contact respiratory monitoring.
• Evaluating the method's accuracy by comparing it with traditional contact respiratory sensors.
• Assessing performance using Mean Square Error (MSE) and Correlation Coefficient (CC).

Main Results:

• The C-band sensing technique demonstrated significant correlation with contact sensors (CC > 0.8).
• Mean Square Error (MSE) values were consistently low (MSE < 0.6).
• The technique successfully identified various breathing patterns, including abnormal ones, in real-time.

Conclusions:

• C-band sensing is a viable non-contact alternative to traditional respiratory monitoring methods.
• This technique can accurately determine respiratory rates and identify diverse breathing patterns.
• It provides a foundation for non-invasive diagnosis and monitoring of respiratory disorders.
