Blood Pressure App: Cuffless Monitoring
- A team at the University of Pittsburgh has developed a smartphone request that could revolutionize blood pressure monitoring, especially for those in underserved communities.
- The app utilizes motion-sensing accelerometers, front cameras, and touch sensors already built into Android smartphones to measure an individual's pulse pressure.
- Vishaal Dhamotharan,a graduate student in the Cardiovascular Health Tech Laboratory,explained the challenge of replicating a traditional blood pressure exam using only a smartphone.
A revolutionary smartphone app developed by bioengineers at the University of Pittsburgh offers a cutting-edge approach to blood pressure monitoring. This innovative tool leverages the sensors already in your phone to measure pulse pressure thru simple hand motions, a significant advancement for those in underserved communities with limited access to customary methods. the app could transform hypertension management by enabling frequent self-monitoring,offering a convenient way for users to share readings with thier doctors. By utilizing this secondary_keyword technology,the app tackles the challenges associated with monitoring systolic hypertension,which affects over a billion adults. this could be especially helpful for those in low-income settings.

Smartphone App Detects High Blood Pressure, Offering New Monitoring Tool
updated June 10, 2025
A team at the University of Pittsburgh has developed a smartphone request that could revolutionize blood pressure monitoring, especially for those in underserved communities. Ramakrishna mukkamala, a bioengineering professor at Pitt’s Swanson School of Engineering, spearheaded the project, which leverages existing smartphone technology to detect blood pressure.
The app utilizes motion-sensing accelerometers, front cameras, and touch sensors already built into Android smartphones to measure an individual’s pulse pressure. Users perform a simple hand-raising motion while holding the phone to get a reading. The findings, published in Scientific Reports, suggest this technology could significantly reduce the global burden of systolic hypertension.
Vishaal Dhamotharan,a graduate student in the Cardiovascular Health Tech Laboratory,explained the challenge of replicating a traditional blood pressure exam using only a smartphone. the team ingeniously used gravity to their advantage.
“Because of gravity, there’s a hydrostatic pressure change in your thumb when you raise your hands up above your heart,” Dhamotharan said. “Using the phone’s accelerometer, you’re able to convert that into the relative change in pressure.”
Sanjeev Shroff, bioengineering department chair and collaborator, sees the research as a promising step toward cuffless blood pressure measurement.
“Growth of a cuffless blood pressure measurement device that does not require any external calibration is the holy grail,” Shroff said. “The research work reported in this publication is an crucial step in the right direction.”
Céderick Landry, assistant professor at the University of Sherbrooke and former postdoctoral researcher, highlighted the significance of pulse pressure in detecting hypertension.
“We showed that if you only have access to pulse pressure, it’s still very correlated with hypertension,” Landry said.
With systolic hypertension affecting over a billion adults globally,the app offers a convenient way to monitor blood pressure and share results with doctors.It is especially beneficial for managing hypertension through lifestyle adjustments.
“This app would be really useful in low-income settings were people may not even have existing access to blood pressure tools,” Dhamotharan said.
What’s next
Mukkamala’s team aims to refine the smartphone blood pressure monitoring technology further, making it readily available to those who need it most. The focus remains on improving accessibility and accuracy for widespread use in hypertension management.
