Another Wearable for BP
From Aktiia (Neuchatel, Switzerland): “The hardware end of the system consists of a bracelet, which the user constantly wears on one wrist. Utilizing an existing process known as photoplethysmography, that device emits pulses of green light which shine through the skin and into the underlying arteries. By analyzing the manner in which that light is reflected back to photoreceptors on the underside of the bracelet, it’s possible to ascertain how the diameter of the arteries change with each heartbeat. That information is in turn utilized to calculate the wearer’s present blood pressure. The data is displayed in real time on a wirelessly-linked smartphone app, which also keeps a record of readings so that users (and their physicians) can see how their blood pressure changes over time. One hundred and fifty readings are automatically performed each week, both day and night, and in multiple body positions.” MORE
