Never before has headgear been so intrinsically linked with actual brain waves. Thanks to a team of researchers looking to create a method for "continuously monitoring high-temporal resolution brain dynamics without requiring conductive gels applied to the scalp," a new baseball cap has been created to do the trick. Said hat conceals five embedded dry electrodes which contact the wearer's forehead, while a single electrode behind the left ear acquires EEG signals. From there, the data is transferred wirelessly and can be processed in real-time to determine a driver's level of drowsiness, for instance. The gurus behind the invention have high hopes for its future, and they've already envisioned it being used in a plethora of medical scenarios and for controlling home electronics. To those about to rock this -- prepare for some serious hat-hair.
