Researchers say watch sphygmomanometers are expected to go on the market

Release date: 2009-05-14



In a breakthrough for health monitoring, American scientists have created a new kind of wearable blood pressure monitor that can be worn on the wrist for extended periods—hours or even days. This innovative device allows continuous tracking of blood pressure, offering valuable insights into cardiovascular health and potentially helping to identify risks of heart disease and stroke early on.

Traditional blood pressure readings taken in a clinical setting can sometimes be misleading. Patients often experience anxiety during medical check-ups, which can temporarily elevate their blood pressure. Moreover, blood pressure naturally fluctuates throughout the day, making a single measurement an incomplete representation of a person's overall condition.

Researchers at MIT have developed a more advanced approach. Unlike conventional sphygmomanometers that require temporarily stopping blood flow to measure pressure, this new device uses a different method. It tracks the speed at which pulse waves travel through the arteries, allowing it to calculate blood pressure without interrupting circulation.

The design is compact and lightweight, resembling a smartwatch. It uses a standard watch battery, making it convenient for daily use. With its ability to provide real-time data, this device could revolutionize how doctors monitor patients' blood pressure over time.

Continuous monitoring not only helps detect irregularities but also enables healthcare providers to better understand patterns and trends in a patient’s blood pressure. This could lead to earlier interventions and more personalized treatment plans for those at risk of cardiovascular issues.

Although still in development, the research team is working on refining the technology to make it more user-friendly, accurate, and affordable. They hope to bring the product to market within the next five years, making this cutting-edge tool accessible to a wider audience. As wearable health technology continues to evolve, devices like this one may play a key role in preventive medicine and long-term health management.
