Possibility of using interdigital sensor (IDS) in estimating different level of blood glucose

This paper presents the relationship of an effective capacitance of the interdigital sensor (IDS) with effective relative permittivity (ε_re) of the material under test (MUT). The relationship of the effective capacitance of the interdigital sensor against the relative permivittivity ε_re is examined by using the curve fitting tool provided by MATLAB. Investigation shows there is a promising new technique in using of the IDS for properties of blood detection. The simulation results are presented and discussed
