Indian-origin researchers develop handy blood pressure app, hardware

In a study, participants with high blood pressure at midlife scored more poorly on tests of attention and executive function later in life.

Neighbourhood Technology Desk/Avi Arya: In order to get the accuracy of cuff devices and the convenience of mobile device apps, a team led by an Indian-origin researcher has created a new app and hardware to measure blood pressure. The technology, details of which were published in the journal Science Translational Medicine along with a video, also includes a discovery of a more convenient measurement point.

The approach uses two sensors an optical sensor on top of a force sensor. The sensor unit and other circuitry are housed in a one centimetre-thin case attached to the back of the phone. Users turn on the app and press their fingertip against the sensor unit. With their finger on the unit, they hold their phone at heart level and watch their smartphone screen to ensure they are applying the correct amount of finger pressure.
