Sometimes the weather changes more rapidly, and we frustrate while wearing and taking-off body warmers again and again. There’s a piece of good news, scientists at the University of Maryland have developed a material which heats up when wearers get too cold. Besides, it also identifies when they feel warm enough, and releases heat. This maintains a perfect temperature balance and avoids excessive heat or cold. Although, the clothing contains classic wool that is used in tracksuits and sportswear. The new thing is, the fabric consists of a super-thin layer of conductive metal. As per researchers, the material comprises of specially engineered yarn along with carbon nanotubes.
The U.S. scientists say the fabric can be helpful to cool or warm up its wearers in accordance to their body temperature. When the conditions are warm and moist, the structure allows heat to pass away. Whereas, in cold situations, it stops the heat from escaping. According to Prof. Min Ouyang, a physicist at the University of Maryland, the human body is similar to a radiator. It releases heat quickly. The researchers say their discovery is a pioneer that can automatically adjust its insulating properties depending upon external circumstances.
The fabric reveals the external conditions with the help of an action-“gating”. In this process, yarn strands coated with metal enables the material to detect the body’s infrared radiation. When there is a rise in the temperature, the tech causes the yarn strands to come closer. The phenomenon opens the fabric’s pores which allows heat to escape. Conversely, in colder conditions, the fabric traps more infrared heat. As a result, the wearer feels warmer. In short, the yarn expands and collapses depending on the temperature and humidity. The fabric can be produced, dyed, and washed similar to that of other sportswear products. The researchers expect their finding will result in comfortable and adjusting clothing. Still, some further work is required before the fabric arrives in the market.
