Wearable Patches That Monitor Blood Pressure Around the Clock
Researchers at MIT have developed a thin, flexible skin patch that continuously tracks blood pressure without a cuff - a breakthrough for hypertension management in underserved populations.
The MIT Breakthrough
MIT researchers developed a soft, flexible patch roughly the size of a postage stamp that adheres to the wrist or chest. Using ultrasound transducers printed onto a stretchable polymer substrate, it continuously measures arterial wall motion and converts that into blood pressure readings without a cuff.
Why Continuous Monitoring Changes Everything
Traditional blood pressure cuffs only capture a snapshot in time, often in a clinical setting that induces white coat hypertension. Continuous monitoring reveals nocturnal blood pressure patterns and stress-related spikes that are strongly associated with heart attack and stroke risk, but invisible to standard checkups.
Path to Accessibility
The MIT team is partnering with manufacturers to bring production costs below $20 per patch. For communities without regular primary care access, affordable continuous BP monitoring could serve as a first line of cardiovascular disease prevention.
