Indycar driver tests smart shirt to track the perils of racing
Japanese mobile giant NTT DoCoMo's Data arm has revealed that it quietly tested its futuristic smart clothing during Indycar races last year. The firm teamed up with driver Tony Kanaan to create a version of its Hitoe garment that's suitable for use in the sport. As before, the shirt is capable of monitoring its wearer's heart rate and muscle activity, learning valuable insights on how the competition affects the body. For instance, Kanaan's heart rate was found to spike when he brought the car to a stop, and while driving, had the same physical stresses as someone who was sprinting.
Japanese 'smart clothing' uses nanofibers to monitor your heart-rate (video)
Japanese mobile carrier NTT Docomo and materials developer Toray have been working on joint projects for a while and now they're publicly announcing one. Welcome Hitoe (Japanese for "one layer"), cloth that contains Toray's nanofibers that are coated in a transmittable layer. It's not the orange cloth (that's just standard material), but the nicotine-patch sized square you attach to it that does the sensing. Place two of these on you and they'll act as electrodes, measuring your heartbeat and even offering metrics resembling a cardiogram. The plan is to connect this cleanly non-invasive health monitor to NTT Docomo's health app platform that's already on its smartphones, developing practical... soft... hardware for sale alongside it. The pitch didn't just include sports clothing, however, with pajamas and other sleepwear planned for launch. Look! There's even a little hat! The sensors will apparently survive tumbles in the washing machine and, having seen an earlier prototype late last year, we can confirm that the patches are suitably lightweight and flexible -- now the work is down to reducing that lumpy hub sensor that we also spotted. Wearable gadgets might finally be going subtle. There's a quick video from our allies at Engadget Japanese after the break.
