Description

It is a ruler with a stress level detector. To find out if you are stressed, tense, calm or relaxed, just place your finger on the liquid crystal sensitive area of the ruler. How does it work? the blood, in moments of tension, does not circulate well and therefore does not reach the ends of the body. This is why cold hands are a clear signal of stress and Stress ruler detects the temperature of the fingers thanks to its body temperature sensitive area. Use our stock layout or you can create your own design to fit your needs. Includes temperature sensitive film to indicate stress levels.
