Abstract

The invention relates to a sensor for measuring a physiological parameter of a subject, comprising: - a body (32) made of electrically insulating material, the body (32) comprising a base (31) and a plurality of protuberances (34) protruding from the base (31), and - a plurality of capacitive elements (37) which are made of electrically conducting material and are embedded inside the body (32), each capacitive element (37) being arranged inside the body (32) at the area of an end of the respective protuberances (34), such that, when the ends of the protuberances (34) are in contact with the skin of the subject, the capacitive elements are at a predefined distance from the skin.

Description

technical field [0001] The invention relates to a sensor with capacitive electrodes, and to a device for measuring a physiological parameter of a subject comprising such a sensor. Background technique [0002] Electrophysiology is the study of these physiological signals that have electrical properties. The most recent measurements are measurements of muscle activity with EMG, recordings of myocardial activity with EKG, or recordings of brain activity with EEG. [0003] These signals can be measured directly at the skin measurement area in a non-invasive manner. [0004] In order to continuously track the physiological condition of the user, the placement of conductive electrodes in contact with the skin measurement area is known. Through electrical contact of the electrodes at the skin measurement area, changes in the potential caused by electrophysiological activity cause changes in the potential of the electrodes. These changes are then recorded directly by electronic ...
