Students at the University of Navarre in Spain are developing a device which analyses the brain waves of the driver to prevent somnolence.

Magnetic field sensors are located in a cap which has a small device at the back to receive data from the sensors and directs them to a PDA which analyses the brain waves and sees if they are normal or if the driver is falling asleep. Then, in the latter case, other devices are triggered to awaken and warn the driver or divert the vehicle from a possible accident.

The researchers estimate that the device would cost 4,500 euro, a price which would be not be too excessive for a bus or lorry driver.
