Apple Inc Patent US20230225659A1 – Biosignal Sensing Device Using Dynamic Selection of Electrodes
BACKGROUND
Patent US20230225659A1: Brain activity can be monitored using electrodes placed on the scalp of a user. The electrodes may in some cases be placed inside or around the outer ear of the user. Measuring of the brain activity using electrodes placed in or around the outer ear may be preferred due to benefits such as reduced device mobility and decreased visibility of the electrodes when compared to other devices that require electrodes to be placed on visible areas around the scalp of the user. However, for accurate measurements of brain activity using an ear-electroencephalography (EEG) device, the ear-EEG device may need to be customized for a user’s ear (e.g., possibly customized for the user’s concha, ear canal, targus, etc.), and may need to be customized differently for different users, so that the electrodes placed on the ear-EEG device may remain in continuous contact with a user’s body. Because an ear’s size and shape vary from one user to another, and because a single user’s ear size and shape, and size and shape of structures such as a user’s ear canal, may change over time, even a customized ear-EEG device may fail to generate accurate measurements at times (or over time). In addition, a customized ear-EEG device may be expensive.
