Abstract Transparent nonvolatile memory fabricated on flexible substrates is expected to meet the requirement of integrated flexible transparent circuits. Here, a simple route to prepare flexible transparent memristors is presented. Flexible transparent conducting Ag grids with low sheet resistance are self‐assembled on polyethylene terephthalate (PET) substrate, and the WO 3 dielectric layer is selectively deposited on the Ag grids via a low‐cost cathodic electrodeposition method under ambient condition. Finally, the Au/WO 3 /Ag grids/PET device exhibits fair good optical transmittance in the visible region, low operating voltages, fast switching speed, and long retention time against electric and mechanical stimulus. Therefore, a universal approach is demonstrated for flexible transparent memristors application by combining Ag grids electrode with cathodic electrodeposition technology.
