Called AdvicyDrive, the wearable monitors your heart rate while driving to determine how awake you are.
If it detects a drop in heart rate, which suggests you're dozing off, it sounds an alarm on a connected smartphone.
When a person falls to sleep their heart rate drops by up around 10 to 30 beats per minute on average.
To detect the most subtle of these changes, AdvicyDrive uses digital photoplethysmography (PPG) - an imaging test used to detect changes in blood flow at the microvascular level on the skin.
It's typically used to monitor blood flow in people with Raynaud's disease, for example, from their fingers and toes.
The technology shines a green LED onto the skin, and based on the variations in colour that are reflected back, the sensor can detect the heartbeat.
It uses a traffic-light system to monitor the beats and will issue a cautionary warning if it begins to drop into the 'amber' section.
The loud alarm rings when the rate reaches the 'red' zone'.

This is just a magnificent idea, actually. Both of them. Now if only they could design a sensor/device to prevent cell phone usage while driving...
