| 摘要 |
The invention relates to an electrophysiological analysis system comprising: a series of electrodes intended to be placed in different regions of the human body; a direct current voltage source; a control device adapted (i) to selectively apply direct current pulses, generated by the voltage source, to a pair of so-called active electrodes, said active electrodes forming an anode and a cathode, and (ii) to connect at least one other so-called passive electrode with high-impedance, said electrode measuring the potential reached by the body; and a measurement device arranged to obtain data representative of the current at the cathode and the potentials on at least some of the electrodes connected with high impedance, in response to the application of the pulses, which data can be used to determine a value for the electrochemical conductance of the skin. The system is characterised in that it also comprises a device for controlling the difference between the potential at the anode and the potential reached by the body, according to the voltage delivered by the direct current voltage source. The invention also relates to an electrophysiological analysis method carried out by the system. |
