For Wuxi’s seniors, climbing stairs and hiking hills just got easier—thanks to a revolutionary smart knee wrap. When 75-year-old Mr. Zhang strapped on the sleek, lightweight device, he was stunned by the instant support: powered by AI, it anticipated his movements, lending muscle exactly when needed. No bulky exoskeleton, just intuitive assistance that made every step feel effortless.     Inspired by mountain goats’ nimble agility, this world-first wearable predicts motion in milliseconds. Going uphill? Its motor delivers a gentle boost to ease knee strain. Heading down? The smart buffering system adjusts stiffness, cushioning joints in real time.     Already a hit in China, with medical endorsements and over 3,000 global pre-orders, the wrap is set to launch overseas in July. Soon, seniors worldwide might find themselves moving with newfound freedom—proving that aging doesn’t have to mean slowing down.
