er that Lance Armstrong was becoming dehydrated while warming up during the first individual time trial of the 2003 Tour de France, when Armstrong lost 6.5 kilos. With the data available from a smart racing suit, the manager would have ordered Armstrong to drink replacement fluids before he launched from the starting line. Another example of performance- and safety-enhancing clothing involves outerwear for snowmobilers. The ensemble includes a machine-washable jacket, vest, trousers, and two-piece underwear. The jacket is embedded with a GSM chip; sensors that monitor position, motion, and temperature; an electric conductivity sensor; and two accelerometers to sense impact. If a crash occurs, the jacket automatically detects it and sends a distress mes- sage to emergency medical officials via SMS. The message includes the rider's coordinates, local environmental conditions, and data taken from a heart monitor embedded in the undershirt. ICT Trends Driving the Broadband Evolution Progress in nanotechnology is also now finding its way into the fashion world. The discovery of carbon nanotubes, along with recent progress in manipulating their conductive properties, has enticed a number of companies into a development race for a new generation of wearable intelligence. Whatever technology is available will be applied to making fabrics considerably more sophisticated, to the point where you won't be able to define whether someone is wearing a textile or a machine. Future plans for clothing are vast and wide, including flexible electronic com- puter displays that will result in outfits that change images, projections, and patterns. Temperature-sensitive fibers could be woven into mood fabrics. The military is financ- ing research into the ultimate camouflage: chameleon fabrics with colors and patterns that would change in response to electrical commands. Smart clothes will likely be powered by photovoltaic fibers, converting light or heat into various functions. If you have seen or read about Harry Potter, do you rememb
