Textile Encoding Inspired by Langer Lines via Elastically Graded Embroidered Tessellations

open access: yesAdvanced Materials, EarlyView.
A standard embroidery machine can encode skin‐like directional mechanics into stretchable fabrics that, when worn, augment the wearer's skin. Zigzag stitch patterns, inspired by skin collagen structure, pack extra slack in threads that, when tessellated, mimic Langer lines.
