The correlation of the complex dielectric constant and blood glucose at low frequency.
A new needle-type sample cell was designed and produced to investigate the correlation between blood glucose and electrical parameters using an impedance analyzer. The characteristics of the measurement cells were optimized to give high sensitivity. High sensitivity complex dielectric constant measurements were obtained by calibration with several known fluids. It was observed that the values of the real (epsilon') and the imaginary (epsilon") dielectric constant increase with decreasing glucose contents in the water/glucose system, and that the value of epsilon' in hamster tail changes according to the variation in blood glucose. It is likely that there is a correlation between blood glucose and the value of epsilon', the electrical parameter.
