Palm eTattoos Measure Stress

  Vidcast:  https://youtu.be/50X2_G70_VM   You’re well aware that your palms get sweaty when you’re under duress, and palm moisture is a time-tested indicator of stress.  Problem is that measurement of that stress level conventionally requires lots of electronic equipment.  Bioengineers at the University of Texas Austin have developed a nearly invisible graphene etattoo that can be applied to the palm.  The tattoos communicate with a smartwatch on the wrist via serpentine graphene-gold connectors that maintain the circuit despite palm and wrist movements.   The signal processing may occur in the watch or in a bluetooth-linked phone permitting non-stop monitoring of your stress levels.   https://www.nature.com/articles/s41467-022-34406-2   #stress #etattoo #smartwatch #bluetooth #sweat
