Abstract

A new construction of a miniaturised contactless electrolyte conductivity sensor based on Pt interdigitated electrodes is proposed. High dielectric permittivity perovskite-oxide films of different composition have been first used as a covering insulator material on metallic electrodes. An equivalent circuit of the sensor is composed and the impedance characteristics are theoretically calculated and experimentally investigated. The operation frequency range and the sensor parameter bilateral dependencies where the sensor exhibits pure active resistance is obtained and evaluated analytically.
