New app measures blood pressure more accurately, which is a novel technology that discovers a more appropriate measurement point, according to the recent study elaborated in the Science Translational Medicine journal.

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. However, the team is still trying to improve the accuracy with applying comprehensive testing using standard protocol set by the Association for the Advancement of Medical Instrumentation.

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. Being able to use your fingertip makes our approach much easier and more accessible.”

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. Other circuitry and sensor units are also compressed in case as slim as one centimeter connected to the back side of the device.

Professor of electrical and computer engineering and senior author, Ramakrishna Mukkamala stated that, “A key point was to see if users could properly apply the finger pressure over time, which lasts as long as an arm cuff measurement. 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.”
