How cool is that!

Scientists have created a fabric that can automatically regulate the amount of heat that passes through it, helping a person stay cool or warm depending on the weather conditions. When conditions are warm and moist, such as those near a sweating body, the fabric allows heat to pass through. When conditions become cooler and drier, the fabric reduces the heat that escapes, researchers said. The researchers from University of Maryland in the US created the fabric from specially engineered yarn coated with a conductive metal. This is first textile shown to be able to regulate heat exchange with the environment, according to the study published in the journal Science. “This is the first technology that allows us to dynamically gate infrared radiation,” said YuHuang Wang, a professor at University of Maryland.  —PTI
