Imagine if a coach could know when a certain player might peak or if a truck driver could know when he’d hit an unsafe point of mental fatigue.

A portable EEG created by University of Pennsylvania professor Michael Platt and postdoctoral student Arjun Ramakrishnan can provide those insights by monitoring brain function. This new technology, which led to the formation of a company called Cogwear LLC, has potential applications from health care to sports performance.

“At its core, the advance we’re making here is the sensor technology. Then we can leverage those signals to make predictions about performance, user experience, customer engagement, all sorts of things,” Platt said.
