A short selfie video on your smartphone can now measure your blood pressure

An exciting new technology, called transdermal optical imaging, can turn your smartphone into an accurate diagnostic device that can measure your blood pressure by analyzing a short video taken of your face. The University of Toronto-led research has demonstrated the system is 95 percent accurate and a smartphone app is already in development.

Considering the awesome computational power that sits in our pockets it is not unexpected that many developers and engineers are working hard to turn our smartphones into super-charged health diagnostic devices.

While many of these compelling innovations require extra add-ons to do things like analyze your breath or test your blood, some of the more extraordinary inventions need nothing more than the smartphone itself. Some impressive recent examples include tracking red blood cells with the phone’s camera and flash, identifying sleep apnea using sonar, and diagnosing ear infections using a simple piece of paper.
