Conventional smart sportswear requires attaching external sensor modules or circuit boards, raising cost and limiting washability. AI Sensing Yoga Wear solves this by weaving deformation-sensing and elastic yarns directly into fabric during manufacturing, making the garment itself a real-time motion sensor with no added hardware-fundamentally different from prior processes that attach electronics onto textiles. The result is a soft, machine-washable garment paired with an AI app for real-time voice-guided posture correction. Production cost and complexity drop by nearly 50%, enabling mass production. The technology creates new industrial value in a smart-textile category extensible to medical monitoring and rehabilitation, aligning with SDG 3 and SDG 9.
