Tencent Digital (Shawn) In addition to bringing daily changes, sweat is actually more important for the human body. Recently, researchers at Northwestern University have developed a skin patch that can detect health conditions through sweat.
Although it sounds like the function of a fitness tracker, the real power of this patch has reached another higher level.
Most fitness trackers only detect calorie consumption, activity, and heart rate, and the functionality of this patch is quite different. Although it is not much bigger than a coin, it is almost equivalent to a laboratory attached to the skin.
For simple fitness purposes, it can remind the user to add electrolytes before they feel water shortage.
The researchers said that after more research, they hope to further refine the use of the patch, such as real-time monitoring of the soldiers' physical adaptation during military training, and even to screen for diabetes and cysts. Fibrosis and other diseases.
The use of this patch is also very simple, you just need to stick it on the skin and start exercising directly. During this time, its internal micro channel collects sweat from the skin and sucks it into different compartments.
Subsequently, the sweat will begin to react with the chemicals therein, and the change in color will indicate sweat loss/acidity, as well as levels of chloride, glucose, and lactate. In other words, these colors represent your body's hydration and electrolyte levels.
More conveniently, you do not need to remember the meaning of different colors. Just take out your smartphone and take a photo with the app that comes with the patch. The app can analyze what the colors represent for you.
After the experiment, the patch can be firmly fixed on the skin of the tester in practical use, and the test result is also very accurate. However, as a research project, the patch still needs to undergo more tests in the future before it can be put into actual production and use.
