Embroidery technology, once rooted in historic hand-stitched garment design, has experienced a remarkable resurgence with the advent of computerization. Due to its unparalleled capacity for material optimization, embroidery offers textile engineers the ability to precisely place single fibers,yarns, fiber bundles, or even wires in a pre-designed geometry. This precision makes embroidery an ideal candidate for integrating functionality into textiles through sensors, actuators, or electrodes. By enabling the automatic integration of conductive fibers and electronic components into textiles,embroidery technology facilitates the creation of e-textiles. This capability opens the door to a myriad of applications, ranging from ECG and EMS electrodes to capacitive, strain and pressure sensors, and even illumination systems and heating elements.Despite the longstanding development of e-textiles, the realization of market-ready products has been limited by high production costs and poor reproducibility resulting from manual production processes. The high degree of automations of embroidery technology, combined with the scalability enabled by multi-head machines, has revolutionized e-textile production. This automation not only reduces costs but also ensures consistent quality, paving the way for the widespread adoption of e-textiles in various industries.
