Abstract

The integration of wearable neural interfaces (WNIs) with the human nervous system has marked a significant progression, enabling progress in medical treatments and technology integration. Hydrogels, distinguished by their high-water content, low interfacial impedance, conductivity, adhesion, and mechanical compliance, effectively address the rigidity and biocompatibility issues common in traditional materials. This review highlights their important parameters-biocompatibility, interfacial impedance, conductivity, and adhesiveness-that are integral to their function in WNIs. The applications of hydrogels in wearable neural recording and neurostimulation are discussed in detail. Finally, the opportunities and challenges faced by hydrogels for WNIs are summarized and prospected. This review aims to offer a thorough examination of hydrogel technology's present landscape and to encourage continued exploration and innovation. As developments progress, hydrogels are poised to revolutionize wearable neural interfaces, offering significant enhancements in healthcare and technological applications.

可穿戴神经界面中的水凝胶。

可穿戴神经接口（WNIs）与人类神经系统的融合取得了重大进展，推动了医疗和技术融合的进步。水凝胶以其高含水量、低界面阻抗、导电性、粘附性和机械顺应性而著称，有效地解决了传统材料中常见的刚性和生物相容性问题。这篇综述强调了它们的重要参数——生物相容性、界面阻抗、电导率和粘附性——这些是它们在WNIs中功能的组成部分。详细讨论了水凝胶在可穿戴式神经记录和神经刺激中的应用。最后，总结并展望了水凝胶应用于wni的机遇与挑战。这篇综述的目的是对水凝胶技术的现状进行全面的检查，并鼓励继续探索和创新。随着研究的进展，水凝胶有望彻底改变可穿戴神经接口，为医疗保健和技术应用提供显著增强。图形化的简介:
