This tiny device sits unobtrusively in your ear. It’s not a hearing aid, nor an MP3 player, but it has the ability to change the lives of millions of people: It monitors and sends brain activity to an app which is able to warn of an impending epilepsy seizure, allowing vital time to seek a place of safety. Besides, it also sends alarms to nominated relatives or friends. Thanks to this device, affected patients will be closer to enjoy a normal life as they'll be able to do things that so far they weren't just in case a seizure happened then.
