The present invention relates to a manufacturing method of a light sensing wire and the like comprising: a primary treatment process for treating a base material containing titanium with an acid solution to prepare a primary treatment material which is the base material whose outer surface is etched; a secondary treatment process for oxidizing the primary treatment material to prepare a secondary treatment material having a controlled surface roughness; a chemical treatment process for preparing a chemically treated chemical treatment material by immersing the secondary treatment material in a titanium precursor solution; and a heat treatment process for preparing a light sensing wire comprising a titanium dioxide material layer in which a titanium dioxide nanostructure is included on the base material by heat-treating the chemical treatment material. Therefore, the present invention is capable of driving without a battery.
