Cutting-edge interconnect design is crucial for flex circuits to achieve optimal signal integrity and transmit signals efficiently among various devices, even under mechanical and electrical strain. In this study, we inspected the suitability of using honeycomb-inspired stretchable connectors in flex circuits, stretched in two orientations: zigzag and armchair under mechanical and electrical stress. The mechanical and electrical deformations were modeled analytically and the same has been confirmed using the finite element analysis (FEA). Out of the two orientations, the resistance and capacitance change in armchair orientation is lesser by 3.6 and 20 times, respectively, compared to zigzag orientation under a strain of 20%, suggesting stability for omnidirectional interconnects in stretchable systems. Honeycomb-shaped connectors present a promising solution for crafting flexible circuits in applications such as smart textiles, soft robotics, and healthcare monitoring systems on curved surfaces, demanding multidirectional stretch capabilities.

适用于大面积柔性电路的蜂窝状互连：仿真和建模

尖端的互连设计对于柔性电路实现最佳信号完整性并在各种设备之间高效传输信号至关重要，即使在机械和电气压力下也是如此。在这项研究中，我们检查了在柔性电路中使用蜂窝状可拉伸连接器的适用性，该连接器在两个方向上拉伸：在机械和电应力下的锯齿形和扶手椅形。对机械和电气变形进行了分析建模，并使用有限元分析 (FEA) 证实了这一点。在这两个方向中，在 20% 的应变下，扶手椅方向的电阻和电容变化分别比之字形方向小 3.6 倍和 20 倍，这表明可拉伸系统中全向互连的稳定性。蜂窝状连接器为在智能纺织品、软机器人和弯曲表面上的医疗保健监控系统等需要多向拉伸能力的应用中制作柔性电路提供了一种有前景的解决方案。
