Area of Science:

  • Biomedical Engineering
  • Sleep Medicine
  • Medical Device Development

Background:

  • Sleep apnea syndrome (SAS) is a prevalent sleep disorder characterized by repeated breathing cessation.
  • Accurate and accessible diagnostic tools for SAS are crucial for timely intervention and management.
  • Current diagnostic methods can be invasive or require specialized clinical settings.

Purpose of the Study:

  • To develop and evaluate a novel, non-invasive system for the detection and analysis of SAS.
  • To create a user-friendly device for at-home application and self-monitoring of SAS.
  • To analyze thoracic body movements for reliable SAS identification.

Main Methods:

  • A system comprising a piezoelectric sensor, microcontroller, flash memory, and laptop was developed.

  • The piezoelectric sensor, attached to the chest, detects mechanical strain from body movements, primarily respiration.
  • Recorded low-frequency data are processed on a laptop to identify SAS based on movement amplitude and frequency patterns.

    • Main Results:

    • The developed system non-invasively detects and analyzes SAS through thoracic movement monitoring.
    • The system effectively captures respiration-generated low-frequency components.
    • SAS detection is achieved by analyzing timed thoracic body movement changes on a laptop.

    Conclusions:

    • The new system provides a non-invasive, self-applicable method for SAS detection and analysis.
    • This technology offers a convenient and potentially more accessible approach for diagnosing SAS in a home environment.
    • Further validation may establish this system as a valuable tool in sleep medicine.
