Figure 4

Temporal changes in emission and blood glucose levels based on periodic measurements taken every 10 min. (a) Time trends of emission and blood glucose levels of subject A. (b) Time trends of emission and blood glucose levels of subject B. (c) Time trends of emission and blood glucose levels of subject C. (d) Time trends of emission and blood glucose levels of subject D. (e) Time trends of emission and blood glucose levels of subject E. The emittance in (a–e) are the average emissions at 9.0 and 9.7 µm, corresponding to the glucose emission peaks.
