This attractive watch is designed by Michael Mathis and Gerda Hopfgartner, the StressWatch is worn on the wrist and monitors heart rate and body temperature in real time. Measurements are taken from the lower part of the watch’s bracelet and displayed on the watch face in recognizable patterns, colors and a bar chart across the top of the watch. Data is then translated into relaxation guidelines and displayed in real time. The black bar graph at the bottom of the watch is the stress line, and if the colors on the watch face are cool greens and blues, you’re pretty laid back. If they turn into hot pink, red or orange, look out. The readings are taken via the lower part of the bracelet and the data gets transformed to guidelines for relaxation.
