An original method for non-invasive glucose measurement: preliminary results

Presents first results obtained using a novel approach for non-invasive measurement of glucose content. We use a network analyzer, which is used to measure T/R, the modulus of the transmission to the reference signal. The under-test solution is placed in the center of a bobbin and plays the role of the self-inductive core. The variation of the "self-inductive medium-core" varies the mutual inductance of the bobbin. We use an electromagnetic signal at a small frequency band about 45 MHz. We have arrived at a measurement of about 0.2 g/liter and the results for the temperature influence on the glucose solution are also presented.
