Forget smartwatches, your clothes could soon track your health

Researchers at the National University of Singapore have developed a battery-free smart textile that can monitor blood pressure in real time through clothing.

The system uses a metamaterial fabric to wirelessly power skin sensors and measure systolic blood pressure continuously, including during physical activity.

Early tests showed accurate readings, suggesting a practical path toward less intrusive cardiovascular monitoring.

If commercialized, the technology could embed health sensing into everyday clothes and reduce the need to charge wearable devices.
