Having your blood pressure taken by a cuff that inflates and deflates around your upper arm is reliable, but it’s not very fast or portable, and it isn’t able to give you continuous measurements over time.
A startup called Blumio is trying a different tactic. It’s building blood-pressure measuring technology that uses radar—typically employed for things like tracking ships or speeding cars by monitoring the phase changes in electromagnetic waves as they reflect off of them—to make it easier and faster to measure blood pressure continuously without needing to squeeze your arm.
