Exmocare Watching Out

Exmocare has developed a wristwatch which will monitor the wearer’s heart rate and heart rate variability, in addition to the wearer’s galvanic skin response and relative movement – along with the emotional and physiological state. This can then be sent to a caretaker, via email, SMS, or instant messaging.

By notifying the wearer and the caretakers of even the slightest physiological changes, the watch can act as a preventative early warning system.

Using a technique called photoplethysmography, the wristwatch measures blood volume pulse (BVP) via infrared LEDs, sending an infrared beam towards the skin’s surface. The watch calculates the BVP by measuring the infrared light reflected from the wearer’s skin.
