1Object-affected harmful factors
If noninvasive optical methods are used to measure glucose concentration, then patient comfort and safety are improved, but measurement precision deteriorates due to interference from tissue properties
Solution Approach 1:
The patent applies force to the tissue to change its physical parameters (density, refractive index, molecular packing) temporarily, which modifies the optical properties and enhances the glucose-specific spectral signal. This allows noninvasive measurement while improving precision by dynamically adjusting tissue parameters to favor glucose detection.
Solution Approach 2:
The applied force acts as an intermediary that modifies the tissue state to improve the interaction between light and glucose molecules. By introducing this mechanical intermediary, the system overcomes the limitation of direct optical measurement through tissue, enabling accurate noninvasive glucose concentration determination.
2Measurement precision
If multiple spectrometer units are used to improve measurement accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the measurement task into multiple spectral regions by using multiple spectrometer units, each optimized for specific wavelength ranges. This segmentation allows simultaneous collection of complementary spectral information, improving glucose measurement precision while distributing the complexity across modular components.
Solution Approach 2:
The patent extends the measurement from a single spectral dimension to multiple spectral dimensions by employing multiple spectrometer units covering different wavelength ranges. This multi-dimensional spectral analysis provides redundant and complementary information, enhancing measurement accuracy despite increased system complexity.
