The parametric analysis provided clear design guidelines for optimizing microwire arrays. We applied these insights to develop two complementary multilayer designs: a high-performance herringbone pattern that maximizes stretchability, and a more robust periodic architecture that balances mechanical performance with manufacturing considerations. A herringbone pattern emerged as a natural choice for a two-layer geometry, as illustrated in Fig. . The design synthesis incorporated our single-layer analysis results, suggesting optimal parameters of wide microwires, short lengths, increased spacing in the direction of strain, decreased spacing perpendicular to strain, and angles of 70°or greater relative to the direction of strain. However, practical design constraints necessitated certain compromises: maintaining a sufficient length-to-width ratio to preserve microwire-like geometry, and ensuring adequate overlap between layers for both feasible alignment and robust electrical connectivity. The latter is particularly important as increased overlap creates redundant electrical pathways, potentially improving resilience against microwire failure. Based on these considerations, we selected the following parameters: 100 µm length, 4 µm width, 20 µm length-wise spacing, 3 µm width-wise spacing, and 70°angle, with each microwire overlapping two microwires of the opposing layer at each end. 4B shows the change of resistance of a 5 mm wide, 8 mm long sample with an initial sheet resistance of 8.3 Ω/sq and conductivity of 6000 S cm -1 , a value in the same order of magnitude as other published fabrication methods . Remarkably, this geometry maintains performance beyond 100% strain with resistance increase (R/R 0 ) remaining below 3 until approximately 80% strain.
