In this work, liquid metal was introduced into a simple co-flow microfluidic system, and we successfully fabricated the liquid metal droplets fiber by solidifying the continuous phase. The law of liquid metal droplet generation was discussed by theoretical analysis, simulations and experiment results, which is a critical guidance for fabricating liquid metal droplets fibers with various parameters. The liquid metal droplets can be selectively exposed to the air during the dehydration process of the continuous phase. In this way, fibers with different morphologies were fabricated, including symmetric mode and asymmetric mode. These kinds of fibers are easily fabricated in large quantities and can be potentially used in water transportation, fog harvesting, soft robots, etc. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

共流微流控系统液态金属液滴纤维制造的理论与实验分析

在这项工作中，将液态金属引入到简单的共流微流体系统中，并通过凝固连续相成功地制备了液态金属液滴纤维。通过理论分析、模拟和实验结果探讨了液态金属液滴的生成规律，对制备不同参数的液态金属液滴纤维具有重要指导意义。在连续相的脱水过程中，液态金属液滴可以选择性地暴露于空气。通过这种方式，制备了不同形态的光纤，包括对称模式和非对称模式。此类纤维易于大量制造，可用于水上交通、雾气收集、软机器人等。© 2024 日本电气工程师学会和 Wiley periodicals LLC。
