In this paper, we have compensated the blood volume in a non-invasive blood glucose measurement method based on Electromagnetic Sensor. In this method, a bobbin has been used as a sensor, which the solution that contains the glucose (i.e. blood) is located in its core. Any change in glucose concentration causes the dielectric the solution parameter variation and hence the impedance of the bobbin changes. The ratio of the secondary bobbin signal to the reference signal of the primary bobbin (T/R) has been measured in RF frequencies and used as an index of circuit impedance changing. Normally we expect that T/R would only changes as a function of glucose, but there are other parameters such as the solution volume which affect our measurements. In this paper, we have presented the measurement setup and the method of changing glucose concentration. We show that the volume change has higher effects on our measurement output. We have proposed a method for compensation of the volume changes. Finally, we have shown that after this compensation, there will be a good correlation between the glucose concentration and T/R.
