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.
