A number of devices, wired and portable, allow you to determine that the surrounding air is contaminated, but Aerochromics has created a different way to alert the user of a poor-quality atmosphere. Aerochromics suggests using specially designed t-shirt models that clearly demonstrate this when fixing certain types of pollution in the environment. showing a florid two-tone pattern in place of the original uniform color. In total, three versions of T-shirts with long sleeves have been created. One responds to an increased concentration of carbon monoxide, the other determines air pollution by solid microparticles, the third recognizes the presence of radioactive substances in the atmosphere. The principle of operation of clothes is not fully disclosed by the manufacturer, but emphasis is placed on their difficult device. So, a T-shirt uses sewn-in sensors to detect contaminant particles, which, when the permissible readings are exceeded, activate thermal panels that display a pattern on clothes. A t-shirt uses certain chemicals added to the paint to detect an increased concentration of carbon monoxide in the air. Upon contact with CO, they change color. Thus, “smart” clothing should inform its owner and others about the danger. True, the question arises – how many such fixations are designed for a T-shirt, given that its price starts at $ 500.
