The science of light-tissue interaction, reimagined through AI — delivering biomarker measurement at the molecular level without a single needle.
Near-infrared light in the 700–2500 nm wavelength range penetrates skin and subcutaneous tissue without ionizing damage. Different biological molecules — glucose, hemoglobin, proteins, electrolytes — absorb specific NIR wavelengths at unique intensities determined by their molecular structure.
iGlutek's 8-channel photodetector array captures the full diffuse reflectance spectrum in milliseconds. Our proprietary algorithm stack then deconvolves overlapping absorption signals to isolate individual analyte concentrations with clinical-grade precision.
8-channel photodetector captures full NIR diffuse reflectance at 50Hz. Hardware-level noise filtering via lock-in amplification removes ambient light interference.
Savitzky-Golay smoothing, multiplicative scatter correction (MSC), and standard normal variate (SNV) transformation eliminate motion artifacts and skin-tone variation.
A 12-layer 1D convolutional neural network extracts spectral features across wavelength neighborhoods, learning absorption fingerprints specific to each analyte class.
A recurrent LSTM module maintains a rolling 30-day physiological baseline per user, compensating for circadian rhythms, hydration state, and individual absorption coefficients.
Bayesian confidence intervals accompany every measurement. Predictions outside the personalized confidence band trigger clinical-grade alerts with physician-ready event logs.
Benchmarked against current clinical standards and consumer wearables in controlled trials.
