Graphene Tattoos Measure Blood Pressure Continually

Blood pressure measurement hasn’t changed much since the invention of the inflatable cuff-based sphygmomanometer in 1881. People can use the device to give readings a few times a day, but that’s not enough to give a holistic view of cardiovascular health. New electronic tattoos made of graphene continuously read blood pressure for days. The ultrathin, light sensors could allow monitoring of a patient’s blood pressure while they go about their daily activities.
