The fabrication of memristors by drop-coating sol-gel Ti(OH)_4 solution onto either aluminium foil or sputter-coated aluminium on plastic is presented. The gel layer is thick, 14\mu m, but both devices exhibit good memristance I-V profiles. The drop coated aluminium foil memristors compare favourably with the sputter-coated ones, demonstrating an expansion in the accessibility of memristor fabrication. A comparison between aluminium and gold for use as the sputter-coated electrodes shows that aluminium is the better choice as using gold leads to device failure. The devices do not require a forming step.
