Abstract: The present invention relates to a method for measuring a physiological parameter of a subject by means of an optical measurement device, said method comprising the steps of: setting into place the optical measurement device (1, 1bis) facing a skin surface (10) of the subject, so that the object focal spot of the optical objective is positioned at a predetermined skin depth, receiving by the photosensitive receiver (4) light rays from the first object focal spot, at the predetermined skin depth, analyzing the light rays received by the photosensitive receiver (4), and comparing the results of the analysis with known data, so as to determine the physiological parameter of the subject.

Abstract: A device for measuring the concentration of a compound present in the blood includes an adjustable substrate suitable for covering a part of the human body, the adjustable substrate including a light source emitting light beams at at least one wavelength in a range ranging from 700 nm to 3000 nm, the light beams being backscattered by the part of the human body constituting a backscattering source, and at least one photodiode receiver, and a method for measuring the concentration of a chemical compound in blood.

Abstract: The invention relates to a sensor for measuring a physiological parameter of a subject, comprising: a body (32) in an electrically insulating material, the body (32) comprising a base (31) and a plurality of protrusions (34) projecting from the base (31), and a plurality of capacitive elements (37) in an electrically conductive material, embedded inside the body (32), each capacitive element (37) being positioned inside the body (32), at an end of a respective protrusion (34), so that when the ends of the protrusions (34) are in contact with the skin of the subject, the capacitive elements are at a predefined distance from the skin.

Abstract: The invention relates to a device for monitoring the breathing of a user comprising: a textile support comprising a tubular portion formed by knitting an electrically insulating majority ground yarn, the tubular portion being able to cover the chest of the user, at least one breathing sensor formed by knitting a detection yarn, the detection yarn comprising an internal core made of an electrically insulating material and an external sheath surrounding the internal core, the external sheath being formed made of an electrically conductive material, wherein the breathing sensor forms a conductive band having a first end and a second end positioned at a distance from each other, the ends being able to be connected to an apparatus for measuring the electric resistance of the conductive band.
