具有纳米/微米级几何尺寸的开放纳米网结构是透明、柔软且可拉伸微电极的重要候选结构。本研究针对由正多边形和直线轨迹组成的三种类型的纳米网建立了解析和数值力学模型。解析模型描述了纳米网的透明度、有效刚度和拉伸性，并且与有限元分析结果相符。在相同透明度水平的基础上对纳米网的力学性能进行了比较。经过验证的解析表达式为设计具有适合生物集成应用的透明度和力学性能水平的纳米网提供了便捷的指导原则。
Open nanomesh structures with nano/micro-scale geometric dimensions are important candidates for transparent, soft, and stretchable microelectrodes. This study developed analytical and numerical mechanics models for three types of nanomeshes that consist of regular polygons and straight traces. The analytical models described the transparency, effective stiffness, and stretchability of the nanomeshes and agree with the finite element analysis. The mechanical performances of the nanomeshes are compared based on the same level of transparency. The validated analytical expressions provide convenient guidelines for designing the nanomeshes to have levels of transparency and mechanical properties suitable for bio-integrated applications.
