The invention relates to a sensor for measuring a vital parameter in the auditory canal of a person or of an animal. The sensor comprises a sensor element attachment (2), which can be positioned at least partially in the auditory canal (8), a sensor element (1), which can be connected to the sensor element attachment (2) and which can be positioned at least partially in the auditory canal (8), and a positioning element (3), which is suitable for positioning the sensor element attachment (2) in the auditory canal (8), wherein the positioning element (3) can be connected, at at least one end, to the sensor element attachment (2), wherein the position of the sensor element (1) in the auditory canal (8) is determined by the depth of penetration of the sensor element attachment (2) in the auditory canal (8), and wherein the positioning element (3) has a suitable shape that reproduces the anatomy of the inside of the ear, and is suitable for pressing the sensor element attachment (2) into the interior of the auditory canal (8) in such a way that the sensor is retained in a stable manner and a continuous measurement of the vital parameter in the auditory canal (8) occurs, wherein the sensor element (1), the sensor element attachment (2), and the positioning element (3) are arranged at least partially in a housing (4) and the housing (4) can be adapted to the anatomy of at least part of the head of the person or of the animal. Thus, a sensor is provided which can be adapted to anatomical conditions, which does not restrict the mobility of the user, which is comfortable to wear, and which ensures optimal seating. At the same time, good signal quality and optimal modulation depth are achieved. |
