This study demonstrates a novel approach to creating thin-film electronic device that offers selective or complete disposability only in on-demand conditions while maintaining stable operation reliability during everyday use. The involves transient paper substrate, combined with phase change encapsulation and highly bendable planarization materials, achieved through simple solution process. substrate used this smooth surface morphology enables the creation of multilayers for devices. It also exhibits superior waterproof properties, which allows proof-of-concept organic light-emitting function even when submerged water. Additionally, provides controlled roughness under repeated bending, demonstrating reliable folding stability 1000 cycles at 10 mm curvature. Furthermore, specific component can be selectively made malfunction predetermined voltage input, entire fully disposed via Joule-heating-induced combustion.
