Wearable sensor technology is in vogue among athletes in all disciplines, and Textronics Inc., Wilmington, Del., has been awarded a patent for its textile-based electrode system by the U.S. Patent and Trademark Office. The stretchy electrodes are incorporated into garments to comfortably monitor the wearer’s heart rate, ECG or other electrical activity. The heart’s electrical pulse travels to a compatible wristwatch or exercise machine via a tiny transmitter snapped into a pocket on the garment—no monitoring straps to chafe, slip or loosen during workouts. The company produces the NuMetrex™ line of monitoring fitness-apparel, including a sports bra, racer tank and cardio shirt for men.
