Fins fashion smart, cool clothing

Researchers in Finland have developed a technology which could lead to the introduction of a temperature-controllable “smart” fabric. The VTT Technical Research Centre claims to have come up with a new high-volume production method for hot embossing microscopic channel structures onto large areas of plastic film at a low cost. One of VTT’s goals is to engineer a smart fabric, adjustable with a mobile app for controlling the wearer’s temperature.
