Elastic, deformable electrodes have attracted substantial interest owing to their applicability in unconventional stretchable devices. In this study, we investigate the effect of tensile strain on the conductive properties of gold nanowire (AuNW) network electrodes with macroscale mesh structures (mesh-shaped AuNW network electrodes) and the mechanism by which the mesh structure affects its conductivity, with the aim of maintaining a stable conductivity as the electrodes are stretched. At 150% elongation, the proposed AuNW macroscale mesh exhibited a relative resistance change ($\Delta R/R_0$) of 11, as opposed to 30 for AuNW network electrodes without a mesh structure. Microstructural analysis revealed that resistance changes in the mesh-shaped AuNW network electrodes depend on the electrode stretching direction and the current direction within the network. Our experimental and analytical results provide a basis for optimizing the mesh design for metal nanowire networks used in stretchable electrodes.

金属纳米线网络的宏观网格设计对可拉伸电极导电性能的影响

弹性可变形电极因其在非常规可拉伸设备中的适用性而引起了极大的兴趣。在本研究中，我们研究了拉伸应变对具有宏观网状结构的金纳米线 (AuNW) 网络电极（网状 AuNW 网络电极）的导电性能的影响以及网状结构影响其导电性的机制，目的是当电极被拉伸时保持稳定的电导率。在 150% 的伸长率下，所提出的 AuNW 宏观网格表现出相对电阻变化（$\Delta \mathrm{电阻}/{\mathrm{电阻}}_0$) 11，而没有网状结构的 AuNW 网络电极为 30。微观结构分析表明，网状 AuNW 网络电极的电阻变化取决于电极拉伸方向和网络内的电流方向。我们的实验和分析结果为优化用于可拉伸电极的金属纳米线网络的网格设计提供了基础。
