Abstract

Fiber-based wearable electronics, distinguished by their remarkable flexibility and robust performance, have emerged as a focal point in healthcare and soft robotics. While significant strides have been made in advancing fiber-based wearable electronics, pursuing multifunctional integration, particularly in areas such as personal health monitoring continues to present significant challenges. In this work, we report the successful fabrication of ultra-elastic and multifunctional core-sheath EGaIn microfibers tailored for wearable motion detection and visual electrophysiologic monitoring. These highly conductive fibers are characterized by an intriguing core-sheath structure, achieved through the uniform coating of EGaIn liquid metal on wet-spun elastomeric microfibers, which are priorly magnetron sputtered with gold nanoparticles (Au NPs) for fast alloying with EGaIn. Prepared core-sheath EGaIn microfibers possess numerous micro-wrinkles on the surface via a simple pre-stretching treatment, thus demonstrating an exceptional sensitivity (GF = 108.3), a fast response time of 82 ms, and remarkable stability. Their superior electromechanical stability and sensitivity under various strain conditions enable reliable and real-time detection of human motion signals, electrooculography (EOG) signals, and visual evoked potentials (VEP). This research offers a novel approach to the multifunctional integration of high-performance fiber-based electronics.
用于可穿戴运动检测和视觉电生理监测的超弹性多功能芯鞘 EGaIn 纤维
基于光纤的可穿戴电子设备具有卓越的灵活性和强大的性能,已成为医疗保健和软机器人领域的焦点。虽然在推进纤维可穿戴电子设备方面取得了长足进步,但追求多功能集成,特别是在个人健康监测等领域,仍然面临着巨大挑战。在这项工作中,我们报告了为可穿戴运动检测和视觉电生理监测量身定制的超弹性多功能芯鞘 EGaIn 微纤维的成功制造。这些高导电性纤维具有引人入胜的芯-鞘结构,是通过在湿法纺制的弹性微纤维上均匀涂覆 EGaIn 液体金属实现的,事先在微纤维上磁控溅射金纳米粒子(Au NPs)以实现与 EGaIn 的快速合金化。通过简单的预拉伸处理,制备出的芯鞘 EGaIn 微纤维表面出现了许多微皱纹,因此具有超高的灵敏度(GF = 108.3)、82 毫秒的快速响应时间和出色的稳定性。它们在各种应变条件下都具有出色的机电稳定性和灵敏度,能够可靠、实时地检测人体运动信号、脑电图(EOG)信号和视觉诱发电位(VEP)。这项研究为高性能纤维电子器件的多功能集成提供了一种新方法。

期刊介绍: Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
