Description

I

The invention relates to electrochemical converters and can be used in analog and digital computing.

Electrochemical active elements are known that contain a closed electrolyte-filled housing divided by a diffusion barrier into an integral compartment and a total electrolyte volume in which electrodes are placed that form a reversible redox system with electrolyte.

Such elements allow you to convert information from a single source.

The proposed active element transforms information from a number of sources, producing at the output a signal proportional to the sum of the output signals taken with specific weights.

This is achieved by the fact that one of the electrodes of the integral compartment is designed as isolated sections with independent output, the ratio of areas of which is proportional to the ratio of the weights of the input signals, and the distance between sections is much larger than the width of the integral compartment. In this case, the input signals are supplied between the electrode sections and the electrode in the total volume of the electrolyte, which is common in the switching circuit.

The drawing shows a schematic structural diagram of the electrochemical active element. In the case filled with electrolyte,

there is an integral compartment 2 separated from the total volume 3 by a diffusion barrier 4. One of the electrodes of the integral compartment is divided into sections isolated from each other with independent leads 5, 6 and

7, the other electrode 8 is solid, its area is usually not less than the sum of the areas of the sectional electrodes. A cylindrical electrode 9 is installed in the total electrolyte volume.

power on Relative to electrode 9, input signals are applied to the electrode sections. The output signal is removed from a resistor 10 connected between the power source II and the output electrode 8.

The output voltage can be represented as

output K (s, L ,,, + 5.in. +, ..., 5 "; Uzh„),

where K is a constant value of the proposed device, depending on the design, electrolyte composition and resistance of the resistor 10;

Si, 52, ..., Sn are weighting coefficients of input signals depending on

design parameters of each section and the integral compartment as a whole. When the parameters of each section are identical, the weighting factors are equal.
