Driver Alertness

Plessey's award winning EPIC™ sensor technology has been creating considerable interest with car manufacturers as it can be used to provide low cost, reliable detection systems for several automotive applications.

Using its EPIC™ (Electric Potential Integrated Circuit) sensing technology, Plessey has developed the WARDEN™, a new heart-rate based driver alertness monitoring system.

Plessey’s WARDEN system senses the electrical impulses of the heart without direct skin contact and can return an accurate R peak signal from the users ECG which can be used to calculate HRV.

The EPIC™ sensor electrodes can be easily and discretely incorporated inside the seatbacks to access the necessary biometric signals and provide earlier warning of drowsiness or health issues than systems based on eye or head movement.
