摘要
在软电子器件中使用水凝胶已在可穿戴和植入式设备领域取得了重大进展。然而,水凝胶电子学仍面临挑战,包括拉伸性与导电性之间的微妙平衡、微型化的复杂性以及易脱水性。本文介绍了一种木质素-聚丙烯酰胺(Ag-LPA)水凝胶复合材料,它具有抗冻性、自粘性、优异的保水性能和高拉伸性(1072%)。值得注意的是,这种复合材料在室温(47.924 S cm-1)和极冷温度(42.507 S cm-1)下都表现出惊人的导电性。研究进一步提出了微流体辅助水凝胶贴片(MAHPs),以促进 Ag-LPA 水凝胶复合材料的定制设计。这种方法提高了保水性,并提供了封装材料的多功能性,使其成为持久软电子应用的理想选择。作为概念验证,我们成功开发了不同应用和尺寸的软电子器件,包括医疗保健监测、环境温度传感和三维弹簧压力监测电子器件。极寒环境的应用范围进一步扩大。嵌入式 Ag-LPA 水凝胶复合材料的导电性揭示了 MAHPs 在极地救援任务中的潜力。可以预见,MAHPs 将影响精密和定制软电子器件的发展,从而开辟工程应用的新领域。
Programmable Microfluidic-Assisted Highly Conductive Hydrogel Patches for Customizable Soft Electronics
The utilization of hydrogels in soft electronics has led to significant progress in the field of wearable and implantable devices. However, challenges persist in hydrogel electronics, including the delicate equilibrium between stretchability and electrical conductivity, intricacies in miniaturization, and susceptibility to dehydration. Here, a lignin-polyacrylamide (Ag-LPA) hydrogel composite endowed with anti-freeze, self-adhesive, exceptional water retention properties, and high stretchability (1072%) is presented. Notably, this composite demonstrated impressive electrical conductivity at room temperature (47.924 S cm−1) and extremely cold temperatures (42.507 S cm−1). It is further proposed for microfluidic-assisted hydrogel patches (MAHPs) to facilitate customizable designs of the Ag-LPA hydrogel composite. This approach enhances water retention and offers versatility in packaging materials, making it a promising choice for enduring soft electronics applications. As a proof-of-concept, soft electronics across diverse applications and dimensions, encompassing healthcare monitoring, environmental temperature sensing, and 3D-spring pressure monitoring electronics are successfully developed. The scenery of an extremely cold environment is further extended. The conductivity of the embedded Ag-LPA hydrogel composite unveils the potential of MAHPs in polar rescue missions. It is envisioned that MAHPs will impact the development of sophisticated and tailored soft electronics, thereby forging new frontiers in engineering applications.
