A "smart muzzle" to analyze the air we breathe
With this muzzle, researchers hope to find a new technique for diagnosing respiratory diseases. Archives
A team of researchers in China has developed smart masks that can analyze the air the user breathes, allowing the vital signs of various respiratory diseases to be monitored on a large scale.
It is known that the air that a person inhales contains volatile and non-volatile compounds inside tiny water points, and some of these particles can reveal important health information that helps determine whether the user has certain diseases, or how the body interacts with some types of medicine.
In order to test this technique, the researchers attached a strip of solid SBME fibers inside the muzzle (N95), and the volunteers in the experiment were subjected to various activities such as eating banana sticks or pieces of garlic, smoking cigarettes, or eating. Cups of coffee, before they are asked to wear the smart muzzle and breathe inside it, according to the website Science Daily, which specializes in technology.
Then the study team removed the fibers from the muzzle, and they were subjected to various chemical tests to find out the compounds inside it. With this method, researchers hope to find a new technique to diagnose respiratory diseases that require patients to wear protective face masks permanently in their daily lives.
