A NEW TECHNOLOGY HAS TO BE INTRODUCED THAT DETECT BLOOD PRESSURE THROUGH A SHORT SELFIE VIDEO IN SMARTPHONES

The study found that we can just measure blood pressure by talking and by taking a short selfie video.The researchers have used this new technology to analyze two-minute videos of the faces of 1,328 Canadian and Chinese adults that were captured with the help of an iPhone.

Researches at the University of Toronto and Hangzhou Normal University has developed a new technology that can turn your smart phone into blood pressure monitoring device by just analyzing a short video film of your face.



Scientists have developed a new technology that can turn your smart phone into a blood pressure monitoring device by just analyzing a short video of your face. The new technology which is called trans dermal optical imaging has been developed by a team of researchers based at the University of Toronto in Canada and the Hangzhou Normal University in China.

One recent smart phone based blood pressure innovation utilize a small case that are attached at the back of your smart phone on which we have to placed fingertip on that sensor that tells us about the blood pressure but now their is no use of that because now we can measure B.P only by making short selfie video.

The researchers discovered that the optical sensor on a smart phone was sensitive enough to capture reflected red light coming off a person's face. This red light is reflected off hemoglobin under the skin, and with appropriately trained algorithms, it can function as an effective metric to measure, among other things, blood pressure.

By this you can see that how the blood is flowing from different parts of the face.the scientist start up working to get this app in all the smart phones.


Another major problem for the research is whether system works for the lighter or darker skin.Now the research is going on the app to make it work for lighter skin or darker skin.
