Abstract

Developing skin-like ionic sensing materials is highly desirable for skin bioelectronics for long-term health monitoring, which is challenging to realize by using biocompatible natural polymer-based biogels. Herein, we engineer a robust natural protein-based ionic biogel with skin-like combinational properties involving stretchability, softness, durability, ionic conductivity, and environmental adaptability, which is enabled by a synergistic effect of biomimetic nanofibrous structures as well as solvent and ionic enhancement. The skin-like mechanics and functionality of the as-designed natural protein-based biogels suggest their further applications in advanced skin sensors for long-term and high-fidelity physiological monitoring. As a proof of concept, we successfully demonstrate high-quality continuous monitoring of electrocardiograms for 1 week under daily life conditions using such natural protein-based skin-like ionic biogels.

具有仿生力学和皮肤传感器多功能的天然蛋白质生物凝胶

开发类皮肤离子传感材料是皮肤生物电子学长期健康监测的迫切需要，而利用生物相容性天然聚合物基生物凝胶实现这一目标具有挑战性。在此，我们设计了一种坚固的天然蛋白质离子生物凝胶，具有类似皮肤的组合特性，包括拉伸性，柔软性，耐久性，离子电导率和环境适应性，这是通过仿生纳米纤维结构以及溶剂和离子增强的协同效应实现的。这种基于天然蛋白质的生物凝胶的类似皮肤的力学和功能表明，它们将进一步应用于高级皮肤传感器，用于长期和高保真的生理监测。作为概念验证，我们成功展示了在日常生活条件下使用这种天然蛋白质类皮肤离子生物凝胶对心电图进行为期一周的高质量连续监测。
