Auxeticity‐by‐Assembly: Interlocking Modular Auxetic Metamaterials with Selectively Activatable AgNW–Graphene Oxide‐EGaIn Composite Interconnects for Scalable Freeform Photovoltaic Modules

Advanced Functional Materials, EarlyView.
Auxeticity‑by‑Assembly converts freeform photovoltaics from cut‑defined layouts to assembly‑defined systems. Standardized interlocking units generate negative‑Poisson‑ratio, reconfigurable architectures, while hinge regions are wired by selectively activatable AgNW–GO@EGaIn composite interconnects and a folding‑enabled interconnector layer. A decimeter‑
