It is good and astonishing news for people who have blood pressure (BP) problems, never thought that one day BP monitoring would become as easy as taking a video selfie.
But in this modern world anything is possible, Researchers from Hangzhou Normal University, in China, and the University of Toronto, in Canada, is working on an innovative approach of BP monitoring which could be quicker, easier, and more convenient way than the routine BP monitoring apparatus.
Researchers have recently worked on a technology called transdermal optical imaging which measures blood pressure by detecting blood flow changes in the facial videos captured through smartphones.
A selfie-style video of the face is required for this medical technology.
In particular, this method uses smartphones’ optical sensors to follow blood flow patterns under the skin.
Ambient light goes through the skin’s outer layer allowing digital optical sensors in smartphones to see and extract blood flow patterns, which is exactly done by transdermal optical imaging models to predict blood pressure.
