Summary:Liquid impedance measurement systems are widely developed as a promised method for analyte detection. The system was using a capacitive model. The object was modeled as a capacitance which then related to the analyte permeability. In this study, a full impedance model formed from the capacitance, inductance and resistance property of the analyte was used. The model which then called an RLC model was constructed in which the analyte properties affect the capacitance, inductance and resistance value of the model at any given frequency. A resonance frequency of the model was exists based on the resistance, capacitance and inductance value. A mixture of water and glucose was used as a measurement model. The impedance spectrum of the RLC model was related to the glucose concentration in water. It was found that the resonance frequency of the system.
