Ear plug with surface electrodes

摘要

An ear plug (200) comprises a shell (206) with at least two electrodes (201-205) adapted for measuring brain wave signals, said electrodes (201-205) being connected with means for processing the measured signals, wherein the contours of the outer surface of the ear plug (200) and the electrodes (201-205) are individually matched to at least part of the ear canal and the concha of the user. The invention further provides a method for producing an ear plug.

主权项

1. An ear plug comprising a shell with at least two electrodes adapted for measuring brain wave signals, said electrodes being connected via a connector to a processor for processing the measured signals, wherein:
contours of an outer surface of the ear plug are configured to individually match at least part of at least one of an ear canal and concha of a specific user such that said outer surface contours are configured to follow contours of said matched part, the electrodes are configured to individually match said part such that a surface of each of said two electrodes to contact the concha or ear canal of the user is shaped to follow the contour of a part of the ear canal or concha to be contacted by said each electrode, and the ear plug is made of a dimensionally stable material for identical positioning in the ear canal each time it is inserted.
