VTT Smart fabric provides “air conditioning” for the wearer – adjustable
VTT, Finland has developed a new high-volume production method for hot embossing microscopic channel structures onto large areas of plastic film at a low cost for use, eg, in wearable technology and cosmetic applications. One of VTT’s goals is to engineer a smart fabric adjustable with a mobile app for controlling the wearer’s temperature. With the high-volume method, microchannels can be produced on large areas of plastic film in a short time. Pumping cold or hot liquid through a network of microchannels enables the temperature control of functional clothes.
So far, the utilisation of microscopic channels for other than diagnostic purposes has been limited by relatively high production costs and the small siz...
