Correlation between blood glucose concentration and signal voltage from the proposed system. The red regression line demonstrates the relationship between invasive glucose reference values and non-invasive voltage signals: (a) from SR1, (b) from SR2, (c) from MR, (d) from ST1, (e) from ST2, and (f) from MT.
