  • Detection of a chemical species in the sweat of a subject
    Patent number: 12336810
    Abstract: 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.
