In 2020, a related iontronic switchable capacitor was proposed featuring transistor-like gating characteristics coined as "G-Cap". The G-Cap represents a three-electrode device with a symmetric nanoporous carbon electrode in an interdigital arrangement (working capacitor, W-Cap) which can be controlled by a third "gate" electrode (GE). Depending on the bias voltage applied to the porous GE, ions can be reversibly depleted or injected out or into the W-Cap leading to an "off" (capacitance is low) or "on" (capacitance is high) state switching of the W-Cap. By controlling the charge carrier density in the electrolyte, the ion transport between the W-Cap electrodes is influenced leading to a device closure. Therefore, the G-Cap shows similar characteristics to a field-effect transistor (FET). In following works, the G-Cap concept could easily be implemented into a monolithic in-plane G-Cap by using an inkjet printing technique. Very recently, the first combination of both CAPode and G-Cap, termed "G-CAPode", was proposed by implementing a hybrid CAPode as a W-Cap with one redox active electrode in a G-Cap assembly resulting in a precise control of the unidirectional charging characteristics and cut-off voltage (the voltage at which the system switches from low to high current and reverse) of the CAPode by the GE. In contrast to the initial proposed working mechanism of the G-Cap (depletion/injection of ions out of or into the W-Cap), the main operating principle of the proposed G-CAPode is based on a controlled potential shift resulting from the connection between GE and CE of the W-Cap. Consequently, the whole working window of the W-Cap (and therefore of the CAPode) is shifted to positive or negative potential values when the GE is negative or positive biased. In the original concept of the G-CAPode, the CAPode is based on a selective surface redox reaction of a parkerite-based electrode (Ni3Bi2S2@Ni) in an alkaline electrolyte (1 mol L -1 KOH). [article submitted to a journal] Due to the ongoing redox reactions of the battery-like CAPode, the device shows remarkable current responses. However, the ongoing faradaic reactions at the heavy metal-containing G-CAPode prohibits their usage in biological related application because they might change the chemical composition of the electrolyte and potentially generate toxic byproducts, a detrimental feature, especially in the context of bioelectronics and iontronics in general. Implementing a fully capacitive-based system by using biocompatible carbon electrodes (like proposed in the original CAPode and G-CAP concept) is therefore advantageous and could expand the applicable material portfolio for the G-CAPode. A purely physical charge storage mechanism is beneficial in terms of cycling ability and more flexible in terms of electrolyte selection. Furthermore, so far, the G-CAPode electrodes are prepared manually in a macroscopic sandwich-like electrode assembly which is inappropriate for implementing G-CAPodes into complex logic architectures requiring typically small, planar electrical circuits. Automatizing the fabrication method of the G-CAPode to guarantee a precise electrode deposition with a high degree of freedom by using the 3D printing technique would be another improvement and further development of the original G-CAPode concept.
