The optimized CAPode device is integrated with a third GE, transforming it into the core of a G-Cap system. This system operates similarly to a transistor, where the current flow between the WE and CE can be switched "on" or "off" by controlling the gate electrode. This switching mechanism allows the G-Cap to regulate the electrochemical processes, effectively acting as a transistor analogue. In transistor-like systems, the gate electrode plays a crucial role in modulating the flow of charge carriers, allowing the device to either conduct or block current.
