Area of Science:

• Biomedical Engineering
• Spectroscopy
• Diabetes Management

Background:

• Diabetes mellitus requires continuous management to prevent complications.
• Current invasive blood glucose meters cause patient inconvenience.
• Development of non-invasive monitoring methods is crucial.

Purpose of the Study:

• To develop a non-invasive blood glucose measurement system.
• To utilize near-infrared spectroscopy for glucose detection.
• To offer a more convenient alternative to invasive methods.

Main Methods:

• A non-invasive system using near-infrared spectroscopy was designed.
• The system included a light source, detector, and computing unit.
• Light (780-1650 nm) passed through glucose solutions in a cuvette.

Main Results:

• The system detected glucose concentrations from 50 to 400 mg/dl.
• Specific wavelength bands (780 nm and 940 nm) reacted with glucose.
• The 940 nm band showed high reliability with an R² of 0.9806.

Conclusions:

• The near-infrared spectroscopy system is effective for non-invasive glucose detection.
• This technology offers a superior method for monitoring blood glucose levels.
• The developed system has significant potential for diabetes mellitus management.
