Smarter Clothes
By Sally Mcgrane/Pavia
At the Eucentre, a research site co-founded by the Italian Civil Protection Department in Pavia, Italy, a young engineer dons a firefighter's uniform that has been in testing for six months. The first prototype of the Proetex project, the ordinary-looking navy blue jacket and pants contain high-tech fabrics that can keep track of a firefighter's vital signs, warn him if the fire is too hot up ahead, provide GPS readings of his position and alert the command center if he has passed out. The Eucentre engineer walks across the room, and the computer screen reacts. The interface reads MOVING: YES.
The same could be said of the $63 million push by the European Commission (E.C.) to develop so-called smart fabrics and interactive textiles. Though the technology was pioneered in the U.S., the Europeans have taken the reins in a bid to revitalize their traditional-textile industry, which has been hammered by Asian competition. "We want to develop state-of-the-art know-how that can't be found in Asia," says Andreas Lymberis, a scientific officer with the E.C. who has championed smart textiles. "Our purpose is to create a new market."
Bringing industry partners like Philips and traditional-clothing and -textile companies together with university researchers from across the E.U. and Switzerland, E.C.-funded teams have already produced prototypes with limited commercial availability, such as a tank top that wirelessly monitors cardiac patients and sports clothes that keep track of breathing. Other projects include fabrics that look and feel normal but are embedded with microcomputers, solar panels and energy-harvesting systems, as well as fabrics that measure blood oxygen levels and track biochemicals in sweat and bedsheets that monitor depression.
The world market for smart textiles is still small--about $550 million in revenue in 2008--but that could double by 2010, according to Massachusetts-based Venture Development Corp. The challenge is to fit applications to the market, says Lutz Walter, R&D manager at Euratex, a group representing the $326 billion European clothing-and-textile industry. "In the medical field, there's high value added. But to be approved as devices takes 10 years," says Walter. "In other areas, it's price: How much are consumers going to be willing to pay for a smart jogging shirt or for a baby suit that detects sudden death syndrome?"
At the Spaulding Rehabilitation Hospital in Boston, researchers are testing a glove made by Smartex, an Italian smart-materials company, that tracks motor functions in poststroke patients. "We've been looking a lot into European groups for wearable tech," says Paolo Bonato, a professor at Harvard Medical School and the director of the Motion Analysis Laboratory at Spaulding. Bonato estimates that fabric-based wearable systems will be commercially viable in two to five years. "The clinical need is there," he says.
The development of these technologies is currently taking place largely in the biomedical and safety fields, but Annalisa Bonfiglio, a professor of electrical and electronic engineering at the University of Cagliari who coordinates the Proetex project, thinks sports could be the sector where the most potential lies. "Sportswear is an extremely powerful means for promoting the acceptance of these new technologies by common people," says Bonfiglio, noting that the technology Proetex develops for rescue workers could easily be used later for sports applications.
Smartex founder and University of Pisa biomedical-engineering professor Danilo De Rossi says there is no way of knowing if Europe will maintain its edge. "Right now we are leading in this field," he says, since Europe tends to be concerned with medicine, social welfare and the elderly, whereas the U.S. tends to focus on military technology. That could change. But in a business driven by technology rather than price, the Euros would still have a fighting chance.
