Graphene Tattoos can be Used to Measure Blood Pressure

Blood pressure is a key vital sign that provides insight into our cardiovascular health. But blood pressure is typically measured only a few times per year by a clinician-;and these measurements might not always be accurate (maybe, for instance, you're nervous at the doctor's office). A wearable device that could monitor blood pressure continuously would provide more informative readings, allowing clinicians to observe trends and detect consequential blood pressure changes, ultimately improving heart health.
