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].

I also don't mean to defend Apple, but isn't this the same idea behind that children's game where you levitate a ball with your brain, combined with a fitness band? None of these readings can be used to interpret your state of mind.
Although if they are able to use them in concert to detect something like a panic attack, I would welcome the technology from a more health-focused device. I can think of multiple instances I would like to have bad mental times softened with a warning, especially now that I know paracetamol helps dampen mental distress.
