a Illustration of the digital embroidery process. Liquid metal fibers consist of perfluoroalkoxy alkane tubing infiltrated with galinstan. b Electrical resistance per length and mechanical robustness of the liquid metal fibers compared to conductive materials used for textile (black color) or flexible (red color) electronics. Mechanical robustness is measured by the tested number of bending cycles. Arrows indicate materials have 10% resistance change happened after the maximum tested cycle. c–e Images of embroidered textiles subjected to folding and twisting. f Image of an embroidered spiral inductor wirelessly powering light-emitting devices in the presence of saline droplets. g Embroidered wireless system comprising a relay for long-range near-field communication between a smartphone and textile sensor node.
