A titanium foil or a titanium sheet is produced by electrodeposition from molten salt using constant current pulse, the method comprising: forming an electrodeposited titanium film on a surface of a cathode electrode made of glassy carbon, graphite, Mo, and Ni, and separating thereafter the electrodeposited titanium film from the cathode electrode by performing one or both of applying an external force to the electrodeposited titanium film and removing the cathode electrode. This enables the electrodeposited titanium film electrodeposited on the cathode electrode to be peeled from the cathode electrode simply and at low cost.

Methods, structures, devices and systems are disclosed for fabrication of microtube engines using membrane template electrodeposition. Such nanomotors operate based on bubble-induced propulsion in biological fluids and salt-rich environments. In one aspect, fabricating microengines includes depositing a polymer layer on a membrane template, depositing a conductive metal layer on the polymer layer, and dissolving the membrane template to release the multilayer microtubes.

In one embodiment, a method for forming a conducting film includes depositing a base layer of a conducting polymer on a substrate, the polymer forming only a weak bond with the substrate, depositing a top layer of a conducting material on the base layer, applying adhesive tape to the top layer, and peeling the tape off of the substrate, removing the top layer along with the tape.

Provided are a metallic foil manufacturing method in which metallic film electrodeposited by electrolysis on the surface of an electrodeposition surface of a cathode is peeled off to form a metallic foil, and the electrodeposition surface used therein is obtained by subjecting a roughened surface, which results from roughening a smoothed surface made of titanium or titanium alloy using a blast treatment, etc., to an oxidation treatment selected from thermal oxidation, anodic oxidation (preferably anodic oxidation carried out while moving the anodic oxidation solution), or a combination treatment of thermal oxidation and anodic oxidation so that the electrodeposition surface has an oxidation layer with a thickness of 30 to 250 nm on the uppermost layer and has a surface roughness R7.JIS of 4 to 10 m.
