A detection apparatus detects at least one chemical species in the sweat of a human or animal subject, the at least one chemical species being selected from the group consisting of nitrogen oxide NO, nitrite ion NO2− and hydrogen peroxide H2O2. The apparatus has a collection element that is intended to be positioned in an investigation zone of an epidermis of the subject, and a detection device has at least one fluid circuit that is coupled to the collection element in order to direct at least one flow of sweat from the investigation zone and an electrochemical sensor having electrodes that are arranged in the fluid circuit, the electrochemical sensor being configured to produce a signal that represents a concentration of the at least one chemical species in the flow of sweat and a signal that represents a flow speed of the flow of sweat.

The present inventor relates to an electrochemical device for measuring the redox state of the skin, comprising at least one working electrode, such as a microelectrode, a counter electrode, and a reference electrode, said electrodes all being fixed into a single support intended to allow each of said electrodes to be simultaneously brought into contact with the surface of the skin to be tested, the electrodes being connected, on the one hand, to a means for imposing a defined voltage between the working electrode and the reference electrode, such as a potentiostat, and, or the other hand, to a device for measuring the intensity of the current generated at the working electrode by the detection of redox species. The invention also related to a method of measuring the redox state of the skin.
