Synopsis
A revolutionary wearable monitor developed by Korean researchers promises to transform blood pressure management. This bandage-like device allows for continuous, real-time monitoring, challenging the traditional methods of BP measurement. With only a fraction of individuals managing hypertension effectively, this innovation could be a game changer in healthcare.
Key Takeaways
- Continuous blood pressure monitoring provides a more accurate health assessment.
- The wearable device is designed to be comfortable and flexible.
- Liquid metal technology enhances adherence to the skin.
- Real-time data can empower individuals in managing their health.
- This innovation could address the public health crisis of hypertension.
In New Delhi, on August 9 (NationPress), a group of researchers from Korea has unveiled a groundbreaking wearable electronic device that adheres to the skin similar to a bandage, facilitating real-time, continuous monitoring of blood pressure (BP) for prolonged durations.
Traditional blood pressure monitors rely on a cuff that inflates around the arm. In contrast, the innovative technology crafted by the team from Seoul National University continuously tracks BP through a compact, flexible electronic patch, capturing global interest due to its practicality and cutting-edge design.
Professor Seung Hwan Ko from the university stated, "This research challenges the conventional notion that blood pressure measurement is cumbersome and only necessary once daily."
He further mentioned, "Our system introduces a novel health care interface capable of detecting and analyzing physiological signals non-invasively and in real time," as detailed in a paper published in the online edition of Advanced Functional Materials.
Worldwide, only 21% of the estimated 1.3 billion individuals with hypertension effectively manage their condition, which is a significant public health issue.
The research team addressed this by creating a continuous BP monitoring technology based on the observation that the time it takes for electrical signals (electrocardiogram) and mechanical signals (pulse) produced simultaneously in the heart to travel to the wrist varies with blood pressure.
They constructed a model that continuously calculates both systolic and diastolic blood pressure by accurately detecting these two signals with each heartbeat and analyzing the outcomes.
Detecting slight changes in the skin due to blood flow is challenging; hence, the team developed an electronic device that naturally adheres to the patient's skin using a unique material known as liquid metal.
Liquid metal remains in a liquid state at room temperature and conducts electricity effectively, making it an ideal material for this electronic device, as it shares the same elasticity as human skin.
To address the high surface tension of liquid metal, the researchers implemented an innovative process termed "laser sintering." This method, which involves heating finely dispersed liquid metal particles with a laser to fuse them, allows for circuit creation at specific desired locations.
Moreover, experiments confirmed that the device retains its functionality even when stretched to 700% of its original length or subjected to over 10,000 stretch cycles.
