Smart skin patches can monitor cardiovascular health in real time

At present, scientists have developed an intelligent skin patch, can warn people when the skin dry, or by identifying changes in skin color, remind you to timely hospital visits. The smart skin patch, about 5 square centimeters, contains thousands of tiny sensors that monitor subtle changes in skin heat. Researchers at Northwestern University and the University of Illinois at Urbana-Champaign have found that when someone has a cardiovascular problem or simply needs skin moisturizing care, smart skin patches can quickly remind them. Smart skin patches can be directly affixed to the skin, 24-hour monitoring of human health status. The wireless technology uses thousands of miniature liquid crystals to detect heat changes on a flexible substrate, and when the patch is discolored, the user knows that there is something wrong with the body. Yonggang Huang, a senior researcher at Northwestern University, said: "We design smart patches with mechanical invisibility, ultra-thin design, very comfortable to wear, just like the real skin of the human body." Now researchers have tested the effects of smart patches on volunteers ' wrists, Yonggang Huang said: We believe cosmetic companies will be very interested in this product, especially its ability to perceive skin moisture, which is portable and non-invasive. It is reported that Yonggang Huang is responsible for the theoretical design and model manufacturing of smart patches, the latest research report published in the recently published journal Nature Newsletter. Smart skin patches are practical, stretching, compressing, or distorting the skin when it stretches, compresses, or distorts it. At the same time, it uses the instantaneous temperature change perception technology, can detect the user skin surface, and measure the blood flow rate, can observe the cardiovascular health condition directly, as well as the skin moisturizing condition. The patch contains 3,600 liquid crystal sensors, when the liquid crystal sensor found that the skin temperature changes will change color, a special algorithm can transform the temperature change data into a precise health report, only less than 30 seconds to complete.
