The team, from Michigan State University in the USA, also discovered a more convenient measurement point.

A team of scientists including Indian-origins have designed the more futuristic smartphone app as well as hardware that can help monitor blood pressure with more accuracy as compared to the existing cuff devices. "Being able to use your fingertip makes our approach much easier and more accessible", said Chandrasekhar, lead author of the study published in the journal Science Translational Medicine.

"We targeted a different artery, the transverse palmer arch artery at the fingertip, to give us better control of the measurement", said Anand Chandrasekhar, MSU electrical and computer engineering doctoral student and the lead author. We were excited when we validated this location.

The new app technology has been developed by integrating two sensors in it, as an optical sensor located on a top of the force sensor. The sensor unit and other circuitry are housed in a 1 centimeter-thick case attached to the back of the phone. The user now has to open the app and press the sensor unit with their finger. When pressing the sensor unit, the user now has to hold their phone at heart level and watch their phone to ensure that they are applying the right amount of finger pressure on the sensor unit.

According to the World Health Organization, raised blood pressure is estimated to cause 7.5 million deaths per year worldwide, about 12.8% of the total of all deaths.

"We were pleased to see that 90 percent of the people trying it were able to do it easily after just one or two practice tries", said Mukkamala. In addition, complications of raised blood pressure include heart failure, peripheral vascular disease, renal impairment, retinal hemorrhage and visual impairment. This development gives patients an advantageous alternative, and keeping a log of day by day estimations would deliver an exact normal, marking down a periodic estimation peculiarity, Mukkamala said.

The new Blood pressure checking mobile app was recently launched.
