Checking blood pressure no longer requires a visit to a clinic or carrying a bulky device everywhere. Advances in wearable technology have made it possible for many smartwatches to estimate and track blood pressure, giving people an easier way to monitor their health throughout the day.

Traditional blood pressure monitors use an inflatable cuff around the arm to measure these values. A blood pressure monitor in watch , however, relies on sensors and algorithms to estimate blood pressure without a cuff. How Does a Blood Pressure Monitor in Watch Work? Most sma...
