New seatbelt technology has been revealed that can monitor heart and breathing rate, issuing a warning alarm if drivers are likely to fall asleep at the wheel.

Developed by Spanish scientists, the system, called HARKEN, also takes a second reading from a special seat cover but cancels out the motion of the car.

Jose Solaz, of the Biomechanics Institute in Valencia, Spain, said: “The variation in heart and respiratory rate are good indicators of the state of the driver as they are related to fatigue."

Nodding off at the wheel is a major problem and may be the cause of an estimated 20% of all road accidents and around 25% of fatal or serious crashes.

Following successful testing of the system on race circuits. Spanish streets should soon see vehicles being put through their paces in traffic scenarios.
