A Wearable Watch to Monitor Blood Pressure?
It seems like it ought to be easy—a wearable watch-like device that continuously monitors blood pressure. But it’s not easy, unless the wearer sits still, as when taking a BP measurement with an arm-cuff device. There have been BP watches with inflatable wrist cuffs—e.g. from Omron Healthcare (Lake Forest, IL)—but a wrist wearable monitor that works continuously while a person goes through normal activities and gives accurate readings remains elusive. However, researchers at the National Institute of Standards and Technology, collaborating with clinicians at Tufts University School of Medicine, are working on a mechanical model, made of silicon, metal and sensors that simulates a human wrist. With that—called “the Crushinator”—they are proceeding toward an accurate watch-like prototype. MORE
