The group, from Michigan State University in the USA, also found a more advantageous estimation point.
The scientist have developed a new app to monitor your blood pressure more accurately than cuff devices.
It is a good time for the smartphones to become more useful than communication.
Electrical and computer engineering doctoral student and study's leading author, Anand Chandrasekhar from the Michigan State University said in a statement that, "We targeted a different artery, the transverse palmer arch artery at the fingertip, to give us better control of the measurement". We were excited when we validated this location.
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.
The approach uses two sensors: an optical sensor on top of a force sensor. Other circuitry and sensor units are also compressed in case as slim as one centimeter connected to the back side of the device.
Users turn on the app and press their fingertip against the sensor unit. With their finger on the unit, they hold their mobile on the most heart level and watch their mobile screen to guarantee they are applying the right measure of finger pressure. "We were pleased to see that 90% of the people trying it were able to do it easily after just one or two practice tries". In addition, complications of raised blood pressure include heart failure, peripheral vascular disease, renal impairment, retinal hemorrhage and visual impairment. While high blood pressure is treatable with lifestyle changes and medication, only around 20 percent of people with hypertension have their condition under control. This new phone app gives patients an advantageous alternative - keeping a log of day by day estimations would deliver an exact BP average, with periodical estimation becoming obsolete, believes Mukkamala. The team is focusing and working on the accuracy part of the invention hopes to pursue more comprehensive testing based on the standard protocol of the Association for the Advancement of Medical Instrumentation.
