Graphene tattoos can continuously measure blood pressure from the wrist, successfully demonstrated by researchers at the University of Texas at Austin. Wrist monitoring will become the norm in the near future. It might not have to be built into a wearable. Tattoos made with graphene can accomplish this continuously for days on end, according to scientists. The technology is rather different from the traditional way of inflating cuffs. By increasing the pressure until no blood is flowing through the artery, readings can be captured. When the cuff deflates, a detectable vibration is generated in the arterial wall, which can be used to calculate systolic and diastolic blood pressure. You don’t have to do anything to get readings from a tattoo. As set by international standards, it continuously captures readings with “Grade A” accuracy, according to researchers.
