Mobility limitation is one of the early signs of disability and functional decline. It is associated with muscle weakness, loss of balance, shaky gait, and joint pain. Therefore, it is crucial to track mobility-related issues over an extended period by continuously monitoring joint motion. On these lines, a team of researchers has created a stretchable knee wearable that may provide notable insights to improve e-textiles for healthcare.
A stretchable circuit was constructed using several flexible electrical components for the smart all-knit knee brace, enabling wireless, continuous real-time detection of knee joint motion much better than the typical bulky and inflexible sensors. The sensor is effective and quick enough to detect human movement; its response time was less than 90 milliseconds for one-step input. It could also detect the smallest change in the joint angle by 0.12 degrees…
