Engineers at the University of California, Berkeley, have developed a prototype of headphones designed to detect brain activity associated with drowsiness. This technology aims to serve as an early warning system for drivers, potentially preventing accidents caused by fatigue. The detection process relies on miniaturizing complex medical diagnostic equipment into a wearable form factor. Miniaturized EEG Technology The core technology behind these headphones is a miniature electroencephalogram (EEG) device. While traditional EEGs are typically bulky machines requiring numerous electrodes attached to a patient’s head to measure electrical activity in the brain, this new prototype condenses that functionality into earbuds that fit comfortably inside the ears. To effectively monitor brain signals, the headphones are equipped with multiple electrodes integrated into a specialized design. These electrodes are positioned to apply gentle pressure against the ear canal, ensuring constant and reli…
