  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, 37$\mu$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.
