Researchers at the National University of Singapore (NUS) have developed a battery-free skin patch prototype capable of continuously monitoring blood pressure. The device operates without the need for external power sources or traditional inflatable cuffs, offering a more convenient and comfortable experience for patients. This innovation relies on a novel mechanism to harvest energy from skin movements, powering the sensors and data transmission. The patch continuously tracks vital signs, providing real-time data without the inconvenience of recharging. This technology has potential applications in remote patient monitoring, chronic disease management, and preventative healthcare. Further testing and development are planned before potential clinical deployment. The research team anticipates this could significantly improve patient compliance and data accuracy in blood pressure monitoring.
