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.

Korea announced a new sensor system for seniors designed to detect falls involving true cellphone technology which triggers a series of calls to be set in motion at the first sign of trouble. The first call goes to the senior in question to ask if there is a problem, one to a hospital’s emergency center, and one to the person’s family. A really good feature is the integrated GPS allowing the possibly injured person to be easily located.
