It looks like an ordinary baseball cap. But when you put it on, the cap
detects and analyzes the electroencephalogram (EEG) signals from your
brain. It can even tell you if you’re getting too sleepy when driving
based on your brain wave patterns. Similar technology could also allow
you to control home electronics such as TVs, computers, and air
conditioners, all by just thinking about them.
A team of researchers from
Taiwan has designed the new bio-signal monitoring system inside a
baseball cap with the goal of making it convenient and easy to use in
everyday life. Since the system is wireless and portable, and can process data and provide feedback in real time, it could be useful for a variety of indoor and outdoor applications.

“This study details the design,
development and testing of a non-invasive mobile and wireless EEG
system for continuously monitoring high-temporal resolution brain
dynamics without requiring conductive gels applied to the scalp,”
researcher Li-Wei Ko from National Chiao-Tung University in Taiwan told
PhysOrg.com.
“This system has online EEG signal acquisition and real-time signal
processing. It can be used in many applications; we just applied it to
driving tasks in this work, such as drowsiness.” Read More...
