Taking Blood Pressure with a Touch on a Smartphone

Blood Pressure App
Engineers at Michigan State University, University of Maryland, and Chonnam National University (South Korea) have built in an optical scanner to a smartphone case which, with an app, allows a blood pressure reading. As this piece says, “the user provides external pressure on an artery in the finger by pressing an optical sensor overlaying a force transducer on the back of a modified smartphone. The phone runs an app to ensure that the user maintains sufficient finger contact while computing brachial artery blood pressures from the finger-based measurements. The authors showed that blood pressure readings were similar using their smartphone device, a standard arm cuff device, and a finger-cuff device in a group of participants. This smartphone-based device could help make measuring blood pressure more accessible.” MORE
