Researchers from the Penn State and Xiangtan University have developed a device that can be used to monitor health conditions using a person’s sweat. The device is embedded in a patch and consists of a small vial containing multiple chambers that has a valve near the opening made of silicone rubber. The device will be applied over the skin near sweat glands to analyze the sweat as there are lots of biomarkers like pH and glucose present in sweat that will be helpful in the diagnosis of a disease. The device would be beneficial for the healthcare industry, especially for athletics, where it can be used to monitor overheating or to arrange exercise levels to ensure excellent performance.
