example 1

[0062]Example 1: An ear device for placement at a human ear and provided with at least two electrodes for skin contact and detection of bioelectrical signals in use, the ear device comprising:

[0063] - a deformable ear canal portion adapted to be placed in said person's ear canal, and

[0064] - an auricle portion adapted to be arranged at said ear outside said ear canal and provided with at least one auricle electrode for detecting bioelectrical signals, said auricle portion comprising a portion connected to said ear canal and adapted to apply The pressure is such that the at least one concha electrode is pressed against the at least one bendable arm on the skin in use.

example 2

[0065] Example 2: The ear device according to example 1, wherein the ear canal portion is provided with at least one ear canal electrode for detecting bioelectrical signals, the at least one ear canal electrode is arranged in a position suitable for being arranged in the ear canal portion The structure deforms while in the ear canal such that the at least one ear canal electrode is pressed against the skin of the ear canal.

example 3

[0066] Example 3: Ear device according to any one of the preceding examples, wherein the ear canal portion is formed such that it only contacts the upper part of the ear canal in use.

Abstract

An ear device for arrangement at an ear of a person and provided with at least two electrodes for having skin contact and detecting a bioelectrical signal when in use, the ear device comprises a deformable ear canal part adapted to be arranged in an ear canal of the person, and an external ear part adapted to be arranged at the ear external to the ear canal and being provided with at least one external ear electrode for detecting a bioelectrical signal, the external ear part comprises at least one bendable arm which is connected to the ear canal part and is adapted to exert a pressure such that the at least one external ear electrode is pressed against the skin when in use.

Description

technical field [0001] The present invention relates to ear pieces for detecting bioelectrical signals. More particularly, the present invention relates to ear pieces that are arranged partly in the ear canal and partly outside the ear canal at the ear, for example in the concha region, and / or in the retroauricular region. Background technique [0002] A bioelectrical signal is here understood to be an electrical potential difference originating from a living body. Well-known examples are electrocardiogram (ECG) signals and electroencephalogram (EEG) signals. Ear parts for detecting bioelectrical signals at the ear are typically used for detecting EEG signals, but can also be applied to detect other bioelectrical signals, such as ECG, electrooculography (EOG) or muscle activity. [0003] EEG signals are electrical signals produced by a person's brain activity. In recent years, EEG monitoring systems have been devised that can be continuously carried or worn by the person ...
