When the temperature drops, we layer up. It’s the natural thing to do—until now. According to ScienceDaily, researchers at the University of Maryland have engineered a new fabric that can automatically change its properties to trap or release heat depending on external conditions.

The textile, made from synthetic yarn with a carbon nanotube coating, is activated by temperature and humidity: making it the first of its kind. 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. Acting like blinds, the individual strands of yarn open and close to transmit or block heat.

We’ve hear about smartphones and “smart cars,” and even such recent developments as the smart highway – but what about a smart textile?

Researchers from Université Laval’s Faculty of Science and Engineering and Centre for Optics, Photonics and Lasers are well on their way to developing clothes that can monitor and transmit biomedical information on wearers.

By using sensor technology and wireless networks, this smart textile will be able to track and transmit this medical information – which has the potential to be extremely beneficial for people suffering from chronic disease, firemen and police offers, and people who are elderly.
