Digitally-embroidered liquid metal fibers for e-textiles

Here, we demonstrate electronic textile systems with functionalities in near-field powering and communication created by the digital embroidery of liquid metal fibers. Owing to the unique electrical and mechanical properties of the liquid metal fibers, these electronic textiles can conform to body surfaces and establish robust wireless connectivity with nearby wearable or implantable devices, even during strenuous exercise. By transferring optimized electromagnetic patterns onto clothing in this way, we demonstrate a washable electronic shirt that can endure repeated mechanical, thermal & chemical stresses; and can be wirelessly powered by a smartphone to continuously monitor the axillary temperature without interfering with daily activities.
