We demonstrate the highest transparent electrode performance among metal meshes fabricated via nanosphere lithography (NSL), achieving an order-of-magnitude improvement in figure of merit FoM (σ DC /σ OP ). Additionally, we present, for first time, application by NSL electromagnetic interference (EMI) shielding, enabled exceptional improvements sheet resistance. Our method produces substrate-embedded PET and glass etching trenches, yielding high-aspect-ratio features with low Embedded structures also exhibit superior robustness during bending tape tests compared to sputtered metallic films on surface. As a electrode, flexible Ag resistance 1.52 Ω/sq transparency 73.1% as well 0.22 58.1%, corresponding FoMs 737 2736, respectively. For EMI achieve shielding efficiency (SE) 34.5 dB visible transmission SE 52.8 58.1% transmission. heater, can reach saturation temperature exceeding 70◦C within 60 s under applied voltage 1.2 V. These embedded hold promise applications requiring ultralow resistance, including heated windows defrosting systems, large-area organic light-emitting diode (OLED) lighting displays, solar cells, shielding.
