A　biaxially　wave-shaped　polydimethylsiloxane　(PDMS)　surface　was　developed　simply　by　using　a　taro　leaf　as　the　template.　The　resulting　leaf-templated　PDMS　(L-PDMS)　possesses　a　microsized　curved　interface　structure,　which　is　greatly　beneficial　for　the　exact　embedding　of　a　silver　nanowire　(AgNW)　network　conductive　film　covering　the　L-PDMS　surface.　The　intrinsically　curved　AgNW/L-PDMS　film　surface,　without　any　dangling　nanowire,　could　prevent　the　fracture　of　AgNWs　due　to　stretching　stress　even　after　cyclic　stretching.　More　importantly,　it　also　exhibited　a　biaxial　stretchability,　which　showed　ultra-stable　resistance　after　continuous　stretching　for　100　cycles　each　in　X-and　Y-directions.　This　biaxially　stretchable　AgNW/L-PDMS　film　could　extend　the　application　fields　in　stretchable　electronics.
