A responsive textile technology that can be infused into any fabric to turn clothing into a product powered by human energy has been recognised as a medical device, ushering in a new era of performance fabrics.

The US Food and Drug Administration (FDA) has determined Celliant-engineered products to be medical devices because they temporarily promote increased local blood flow at the site of application in healthy individuals. The technology of parent company Hologenix represents the first of its kind to secure FDA designation.

"Our technology can be used in everyday products – t-shirts, clothing, bedding, even airplane seats – to create an increase in local blood flow thereby increasing energy, boosting performance and speeding muscle recovery," says Seth Casden, Hologenix CEO.

"We believe that Celliant is a truly disruptive technology that has transformational applications for textiles. We're currently evaluating additional applications of Celliant in the healthcare space, where, for example, people who suffer from diabetes might benefit from increased blood flow to body tissue."

Celliant-engineered products are designed to harness and recycle the natural heat emitted by human beings to boost performance and rebuild and recharge the human body after physical activity and while you sleep. Celliant is made of a patented blend of thermo-reactive minerals infused into the core of fibre used to create all types of textiles and fabrics so it does not wash or wear out.

Products made with Celliant fabric absorb and convert body heat into infrared energy (IR) that is recycled back into skin and tissue in a safe, natural way. IR is a vasodilator, increasing blood flow to tissue and muscles throughout the body, which delivers vital nutrients and oxygen to the cells.

Celliant is being used in a range of textiles and applications, including the Xcel Infinity Comp TDC Full Wetsuit allowing the wearer to surf longer and recover faster, the Salewa Puez TirolWool Half Zip Jacket that keeps the wearer "energized and warm" for longer, and the Tecnica Mach 1 Pro Women Ski Boot that addresses the need for warmth, comfort and performance. These are expected to be released in the autumn.

"Science has shown that infrared energy increases blood flow, improves muscle recovery and reduces long-term pain," adds Dr. Michael Hamblin, principal investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital. "The FDA's determination of Celliant products as medical devices and general wellness products will likely spur interest in infrared technologies and further development of garments and wraps that can positively impact people's well-being."
