Next week, the first Wearable Technologies Congress will be held in Munich. Some of the items include jackets that protect against extreme heat or cold and a solar shopping bag similar to the Solar Beach Tote we recently showed you. What really attracted our attention was the German beurer GmbH Beltless Heart Rate Monitor. Based on the impressive science known as plethysmography, a sensor measures light reflected by the bloodstream through your finger artery. We think it would be novel if we knew we were going to have a heart attack before we actually biked it up that steep hill ahead.
