We report on a hybrid manufacturing approach for electrochemical transistors (ECTs) based on conventional printing, digital printing, laser processing, and post-press technologies. A careful selection of the conductive, dielectric and semiconductor materials with respect to their optical properties allows for a significant reduction of registration problems that apply when structuring is done only by additive techniques, enabling fabrication of ECTs on large areas. We produced a matrix of 50x17 ECTs on format DIN A4 (210 × 297 mm 2). The prototype components based on this technology operate at gate voltages in the range of IV and show on-off ratios of 10 2.
