Release date: 2014-11-19 Researchers at Northwestern University and the University of Illinois at Urbana-Champaign have developed a faux-leather wearable medical device that can quickly alert people with cardiovascular problems or moisturize their skin. The research results are published in the latest issue of Nature Communication. According to a daily report by the Science Network and the Physicist Organization Network, the small device is about 5 cm square and can be placed directly on the skin for health monitoring around the clock. The wireless technology uses thousands of tiny liquid crystals on a flexible substrate to sense temperature. When the color of the device changes, the wearer knows which part is out of order. Huang Yonggang, a senior researcher at Northwestern University, said: "Our equipment is an invisible machine. It is ultra-thin and comfortable, just like the skin itself. The device can be tested on people's wrists. It is conceivable that cosmetics companies will have Interest in this portable, non-invasive way to measure the dryness of the skin. This is the first device in its class." This technique uses transient temperature changes on the surface of the skin to determine blood flow, which is directly related to cardiovascular health, skin hydration levels (when the skin is dehydrated, its thermal conductivity characteristics change). Zhang Hui, an assistant professor of civil and environmental engineering research at Northwestern University, said that the device is very practical. When your skin is stretched, compressed or twisted, the device is stretched and compressed. Or distorted." The device contains up to 3,600 liquid crystal arrays arranged on a thin, flexible, stretchable substrate. With 3,600 liquid crystals, the photonic device has 3,600 temperature points and provides sub-millimeter spatial resolution, equivalent to the infrared technology currently used in hospitals. However, infrared technology is expensive, its use is limited by clinical and laboratory settings, and new equipment is low cost and portability. The researchers say that when the crystal senses a change in temperature, it changes color. An algorithm converts the temperature data into an accurate health report, all of which is generated in less than 30 seconds. John A. Rogers, a co-author of the paper and a professor of materials science and engineering at the University of Illinois, said: "These results provide an example of the first 'skin' photon sensor, which greatly expands the range of functions attached to skin devices, beyond The possibility of using electronic products alone." This technology and related essential drugs have been demonstrated in this study, although additional testing is required before the device is put into use.
