New Apple patents crop up all the time, but one recent filing has received particular attention for what it could mean for the future of wearable tech in health tracking. A patent filed with the US Patent & Trademark Office describes what looks and sounds like AirPods with biosensors that can track brain activity.
Electrodes in the housing of the earphones would measure biosignals and electrical activity from the brain. That could include electroencephalography (EEG), electromyography and electrooculography (see our guide to the best AirPods Pro 2 prices for Apple's latest inner ears).
