In addition, wearable biomonitoring sensors based on atomic materials have emerged as the ideal film for conformal unobtrusive sensing of physiological signals. We have pioneered these materials as electronic tattoos for monitoring diverse electrophysiological signals and vital signs with the advantages of positional stability and negligible motion artifacts. These advantages have been fully exploited based on the bioimpedance modality and artificial intelligence to enable a continuous blood pressure wearable biosensor based on graphene. We show the possibility to record thousands of blood pressure points per subject with IEEE Grade A accuracy, which is equivalent to clinical accuracy. Advancing this wearable unobtrusive platform for ambulatory and clinical uses could contribute in reducing cardiovascular disease, which is the leading cause of mortality.
