Abstract
An example device includes a first magnetoresistance sensor configured for detecting magnetoencephalography (MEG) signals from a first ear cavity of a user. The example device also includes a first enclosure configured to magnetically shield the first magnetoresistance sensor. The first magnetoresistance sensor is positioned entirely within the first enclosure, and the first enclosure has an opening through which the first magnetoresistance sensor is configured to detect the MEG signals propagated from the user to the opening of the first enclosure. The example device further includes circuitry coupled to the first magnetoresistance sensor and configured to monitor brain function of the user based on the MEG signals. Methods for detecting a magnetic field from an ear cavity with a magnetoresistance sensor are also disclosed.
