Description

Promising approaches to improving noise immunity, expanding the range of operating frequencies of biosensor systems of the electrochemical type are investigated. The concept of expanding functionality, increasing information productivity, as well as ensuring the metrological reliability of biosensor systems of the electrochemical type is formulated. In the process of research, the general structure of a multi-frequency electrochemical analyzer was developed, requirements for its main elements, calculated determining parameters of circuits and electrical signals were formed. A detailed block diagram of a multi-frequency electrochemical biosensor analyzer has been developed, the composition, functions, informative and control signals of measuring transducer unit nodes with potentiostat and galvanostat modes based on a bridge circuit with partial balancing and the ability to bring the phase of the bridge output signal to zero and directly transforming it have been determined amplitudes. The structures of the submodules of the measuring channel for the implementation of the basic methods of electrochemical research are developed. The optimal structural solutions of the test signal generator and the informative signal conversion unit in the frequency range 0 - 1 MHz were selected. The issues of their optimization for coordination in the general structure of the basic measuring module are resolved. The necessary experimental studies on the mock devices.
