Herein, we present the first example of a G-CAPode which is purely based on physical electrosorption. The two electrodes of the W-Cap consist of porous materials with well-defined but largely different nanopore sizes fabricated via inkjet and extrusion printing techniques (Figure ) using a recently developed carbon precursor. Integration of a third electrode as GE by extrusion printing affords the novel G-CAPode architecture. The gate electrode allows to control the onset potential of the printed CAPode by regulating the applied bias voltage (Ubias) between GE and CE enabling a precise and flexible tailoring of the output signals of the whole ionic diode device (Figure ) resembling the features of an I-MOS varactor. In-depth electrochemical characterization of the switching principle of the printed G-CAPode was the basis to integrate the device into various AC filtering architectures demonstrating their great potential as a switchable device combining both, ionic diode as well as ionic transistor properties in one device.
