In article number 1800033, Lei Wei, and co‐workers demonstrate a stretching‐induced alignment method to achieve globally and highly oriented electrospun P(VDF‐TrFE) nanofibers on a large scale. The resulting highly aligned nanofiber bundles are woven into daily outfit for body motion sensing. The demonstration of monitoring body gestures including angles of elbow bending and directions of a swinging arm may lead to the further development of motion‐tracking technology.
