A simple way to create conductive textiles by coating fabric with liquid metal (LM) particles is reported. The coating process involves dip-coating the fabric into a suspension of LM particles at room temperature. Despite being coated uniformly after drying, the textiles remain electrically insulating due to the native oxide that forms on the LM particles. Yet, they can be rendered conductive by compressing the textile to rupture the oxide and thereby percolate the particles. Thus, compressing the textile with a patterned mold can pattern conductive circuits on the textile. The electrical conductivity of these circuits increases by coating more particles on the textile. Notably, the conductive patterns autonomously heal when cut by forming new conductive paths along the edge of the cut. The textiles prove to be useful as circuit interconnects, Joule heaters, and flexible electrodes to measure ECG signals. Further, the LM-coated textiles provide antimicrobial protection against Pseudomonas aeruginosa and Staphylococcus aureus. Such simple coatings provide a route to convert otherwise insulating textiles into electrical circuits with the ability to autonomously heal and provide antimicrobial properties.}, journal={ADVANCED MATERIALS TECHNOLOGIES}, author={Yang, Jiayi and Nithyanandam, Praneshnandan and Kanetkar, Shreyas and Kwon, Ki Yoon and Ma, Jinwoo and Im, Sooik and Oh, Ji-Hyun and Shamsi, Mohammad and Wilkins, Mike and Daniele, Michael and et al.}, year={2023}, month={Apr} }

While spraying has been used previously to deposit many materials, including liquid metals, this work focuses on quantifying the spraying process and combining it with silicones. Spraying generates liquid metal microparticles (~5 μm diameter) that pass through openings in a stencil to produce traces with high resolution (~300 µm resolution using stencils from a craft cutter) on a substrate. The spraying produces sufficient kinetic energy (~14 m/s) to distort the particles on impact, which allows them to merge together. This merging process depends on both particle size and velocity. Particles of similar size do not merge when cast as a film. Likewise, smaller particles (<1 µm) moving at the same speed do not rupture on impact either, though calculations suggest that such particles could rupture at higher velocities. The liquid metal features can be encased by spraying uncured silicone elastomer from a volatile solvent to form a conformal coating that does not disrupt the liquid metal features during spraying. Alternating layers of liquid metal and elastomer may be patterned sequentially to build multilayer devices, such as soft and stretchable sensors.}, number={2}, journal={MICROMACHINES}, publisher={MDPI AG}, author={Neumann, Taylor V. and Kara, Berra and Sargolzaeiaval, Yasaman and Im, Sooik and Ma, Jinwoo and Yang, Jiayi and Ozturk, Mehmet C. and Dickey, Michael D.}, year={2021}, month={Feb} }
