You don’t need a blood pressure cuff anymore, researchers at the University of Texas now can make a graphene tattoo that monitors your blood pressure continuously.

Blood pressure is one of the most important vital signs, changes in blood pressure can be deadly.

“To make the tattoos, the researchers grow one or two layers of graphene on copper foil, coat it with an ultrathin 200-nanometer-thick layer of acrylic, and transfer it to commercial temporary tattoo paper. Graphene’s atomic-level thickness means the patches conform to skin really well, Akinwande says, so they stick without the need for adhesives and stay in place. Plus, the wearer doesn’t feel them.”

This is a bit of a leap from the sensors athletes wear, I can see this entering mainstream rapidly.
