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[2:1]. Users could potentially activate measurements through simple gestures like tapping the AirPods tip[2:2].
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].


In 2021, writer and game designer Alex Blechman inadvertently created a meme:
_Sci-Fi Author: “In my book I invented the Torment Nexus as a cautionary tale.”
Tech Company: “At long last, we have created the Torment Nexus from classic sci-fi novel Don’t Create The Torment Nexus!”_
So… There’s Apple working away on building yet another version of the Torment Nexus.
