Abstract Recently, green electronic products are receiving increasing attention from scientists. Here, biodegradable lateral capacitively coupled electric-double-layer (EDL) oxide-based thin-film transistors (TFTs) were fabricated on a flexible paper substrate. The TFTs exhibit good performance due to the extremely high EDL capacitance of the egg albumen based electrolyte. Good transistor performances against mechanical stress were observed. In the coplanar double-gate structure, the high-low level of the different periods is input to the two gates to realize the logical function ‘AND’ operation. Resistor loaded inverters were built, exhibiting full-swing amplitude and high-voltage gain at low operating voltages, and implementing ‘NOT’ logic function. And the inverters were used to realize the conversion of the noise signal to the two-bit output. Therefore, the proposed lateral capacitively coupled TFTs may have potential applications in low-cost green portable logic computing devices.
