Graphene “e-tattoo” Measures Blood Pressure

“The new device makes its blood pressure measurements using a new method, so the team had to develop machine learning models to analyze the readings. It works by firing an electrical current into the skin and measuring how the body reacts – a value called bioimpedance, which has an indirect correlation with blood pressure that the new models can calculate.  In tests, the e-tattoo was able to accurately monitor blood pressure in arteries for more than 300 minutes. Ultimately, the team hopes to develop the tech into e-tattoos that can be worn by patients long-term to measure their blood pressure in a range of situations, including sleeping, exercise, and during stress.” MORE
