SmartCap Technologies, based in Brisbane, Australia, makes a trucker's cap that can detect when the wearer is getting drowsy. It triggers a smartphone alarm or, if the danger of falling asleep is extreme, alerts a supervisor or dispatcher. The smart cap works by tracking brain waves using sensors that, like an EEG, measure microvolts of electricity on the wearer's forehead. They also produce safety helmets.
