Transparent alpha-MoO3 belts, featuring millimeter-scale side lengths and micrometer-scale thicknesses, were produced through a one-step sintering process using metallic molybdenum powder. When affixed to stretchable substrates, the alpha-MoO3 belts demonstrated robust mechanical stability under continuous and sustained tensile strain in the longitudinal direction. The belts exhibited a transmittance exceeding 68 % in the visible and near-infrared light regions. The current between gold dots on belts fixed to a stretchable polydimethylsiloxane substrate increased with the application of tensile strain. Furthermore, a CoFe2O4 thin film deposited at elevated temperature onto an alpha-MoO3 belt exhibited significant magnetic anisotropy. These findings introduce a novel and efficient approach for fabricating highly crystalline thin films on stretchable and bendable substrates using alpha-MoO3 belts.
