A new sensor that follows the health condition by analyzing sweat

Researchers at the University of Washington have developed a new three -dimensional sensor to follow up the state of health and diagnose general diseases such as diabetes, gout, kidney or heart disease, depending on the monitoring of glucose levels, lactate and uric acid, in addition to their sweat rate during exercise. According to the research article, Chuchau Chen, a PhD student at Washington State University and the first author of the research article, indicated that 3D printing could make a difference in health care fields, and the research team tried to integrate 3D printing techniques in a practical and effective way. The researchers used 3D printing to create a preliminary model for the new sensor, through a new manufacturing process, as researchers used a single atomic catalyst and enzymatic interactions to improve low levels of important variables. The new, bearable sensor carries three biological sensors, which change the color, to indicate that it reaches certain levels of the concentration of biochemicals. And sweat contains many important sides that express the health level, but unlike blood samples, it does not need the patient to feel pain during the analysis. Urienic acid levels in sweat may indicate the risk of gout, kidney disease or heart, as glucose levels are used to monitor diabetes, and lactate levels may indicate the severity of the exercise. “The pace of sweat is also an important physiological indicator of people’s health,” said Kayan Chey, an assistant professor at the College of Mechanical Engineering and Engineering Materials. But the researchers noted that the amount of these chemicals in the sweat is very small, which sometimes makes their measurement difficult, in addition to the need for specialized equipment and experience in producing it to develop and produce it. “It is an innovator to use atomic stimuli to improve the sensitivity and accuracy of the health awareness device,” said Annie du, a research professor at the College of Mechanical Engineering and Engineering Materials, which led the study with Chio. The new supervision apparatus, its manufacture, is made of flexible and expandable materials, and also contains small channels to measure the sweat of the sweat and the concentration of important signs. Annie added: “We need to measure the small concentrations of important signs, so we do not want these supporting materials to be present, or that we should remove them. For this reason, we use a unique way to push micro -ducts with self -examination.” When the researchers compared the monitoring devices on the voluntary arms to the results of the laboratory, they found that the new monitoring device provides the highest accuracy and reliability of the concentration of chemicals, in addition to the sweat rate. While the researchers initially chose three important signs of measurement, it is possible to add more, and the device has also given a noticeable ease to the volunteers when they carry it.
