In this work, we present a new method for a planar interdigital transducer to determine the electrical parameters (relative permittivity, capacitance and thickness) of the double layer (DL) on the surface of the electrode loaded by a biological medium. A theoretical approach has been proposed to define these parameters. The CoventorWare software was used to simulate the model design of interdigital transducer. The simulation results show that the method can determine the parameters of double
