摘要:
The invention relates to a method implemented in a system comprising: - a series of electrodes, - a DC voltage source, - a control device, suitable for connecting a pair of so-called active electrodes to the voltage source, said active electrodes forming an anode and a cathode, and for connecting at least one other so-called passive electrode, with a high impedance, said electrode being used to measure the potential reached by the body, and - a measuring device, the method comprising a measuring step comprising the application, to the anode, of DC and constant voltage time slots, and the acquisition of data representative of the current flowing between the electrodes and the potentials on electrodes connected with high impedance, the voltage applied to the anode during the measuring step decreasing between each slot and the subsequent slot, the duration of the first voltage slot being greater than the duration of the following slots, and being suitable for stabilising, as of the first slot, oxidation of the anode causing an overvoltage of said anode, the method further comprising, after the application of the voltage time slots, deducing the value of the overvoltage of the anode, and using the overvoltage to determine an electrochemical conductance of the skin for a determined potential difference between the anode and the body. The invention also proposes a system for implementing this method.Linvention propose un procédé mis en œuvre dans un système comprenant : - une série délectrodes, - une source de tension continue, - un dispositif de commande, adapté pour connecter une paire délectrodes dites actives à la source de tension, lesdites électrodes actives constituant une anode et une cathode, et pour connecter au moins une autre électrode, dite passive, en haute impédance, ladite électrode servant à mesurer le potentiel atteint par le corps, et - un dispositif de mesure, le procédé comprenant une étape de mesure comprenant lapplication, à lanode, de créneaux de t
