Abstract: FIELD: measurement equipment. ^ SUBSTANCE: group of inventions refers to medical technology, and namely to methods for determining bioelectric potential by means of set of electrodes. Disposable electrodes are used in methods for determining bioelectric potential to measure electric potentials on the skin of an animal or a human. Each of them includes carrier; three sensors located on the carrier so that the lines passing through centres of the appropriate pairs of sensors specify two linearly independent directions; device of detachable attachment of electrodes to the skin; connections to external equipment; and visual indication of preliminarily specified electrode orientation. In order to measure electric potentials in pre-determined locations, electrode of the set of electrodes is located in them so that two linearly independent directions specified with the electrode in the first location coincided with two linearly independent directions of electrode in the second location. Wireless transmitter is connected to each of the electrodes and the signals transmitted with it are received from each transmitter. As per the other version of the method, each electrode has at least three sensors located so that the lines passing through centres of the appropriate pairs of sensors specify two linearly independent directions. Each of the above sensors on each electrode measures electric potential of the skin, transmits the signals reflecting at least two differences between pairs of potentials, and electric potential is determined in the first location relative to reference location on the basis of the received signals. As per the third version of the method, in the first location there measured is electric potential (VAr) at the first reference point, electric potential (VAdirX) is measured at the point located in the first direction from the first reference point, the first difference (VAdirX)-(VAr) of electric potentials is determined, electric potential (VAdirY) is measured at the point located in the second direction from the first reference point, the second difference (VAdirY)-(VAr) of electric potentials is determined, signals reflecting the first and the second differences of electric potentials are transmitted. In reference location the electric potential (VRr) at the second reference point is measured, eclectic potential (VRdirX) is measured at the point located in the third direction from the second reference point, the third difference (VRdirX)-(VRr) of electric potentials is determined, electric potential (VRdirY) is measured at the point located in the fourth direction from the second reference point, the fourth difference (VRdirY)-(VRr) of electric potentials is determined, and the signals reflecting the third and the fourth differences of electric potentials are transmitted, transmitted signals are received and electric potential of the first location is determined relative to reference location. In order to implement methods of measuring electric potentials on the skin of an animal or a human, the system containing the microprocessor having the possibility of performing the reception steps and determining the above methods is used. ^ EFFECT: use of group of inventions will allow enlarging the number of available methods for determining bioelectric potential. ^ 13 cl, 9 dwg
