Study Evaluates Sensor Technologies On Popular Smartphones

Researchers at the University of California, San Francisco (UCSF) and Sage Bionetworks announce the launch of “My BP Lab”, a research study that uses surveys and sensor data collected from participants’ phones to quantify and understand their daily stress. The study leverages an optical sensor embedded in the Samsung Galaxy S9 and S9+ smartphone to derive estimates of heart rate and blood pressure. With My BP Lab, participants can track variation in their blood pressure relative to daily experiences over the course of the three-week study.


Wendy Berry Mendes, UCSF Professor and Principal Investigator of the My BP Lab study, shares, “My BP Lab" uses sensor data from Samsung Galaxy S9 & S9+ phones to track how stress affects blood pressure changes. This study potentially will provide the largest dataset ever obtained on stress levels, health behaviors, and physiological responses during one’s daily life. By collecting subjective experiences, behaviors like sleep and exercise, and blood pressure levels across a three-week period, we can identify the most important triggers of stress physiology.”
