Apple has patented a new AirPods sensor system that integrates active and reference electrodes into the housing and tips to measure brain activity and other biosignals[^1]. The system can monitor electroencephalography (EEG), electromyography (EMG), and electrooculography (EOG) through electrodes placed around the outer ear[^2].
The technology uses dynamic electrode selection, intelligently choosing specific electrodes based on user parameters and wearing conditions to optimize accuracy[^2]. Users could potentially activate measurements through simple gestures like tapping the AirPods tip[^2].
However, experts note significant challenges - current in-ear EEG systems require patient-specific 3D ear scans and careful cleaning procedures that may not align with Apple's consumer product approach[^3].
