In this study, we define our DeviceHub as an open cell, miniaturized 3-electrode-cell setup. known as the SDC . This setup consists of a gold reference electrode (RE) and a platinum counter electrode (CE), both positioned within a movable cell housing made from polytetrafluoroethylene (PTFE). This housing utilizes electrode spots on a planar substrate functioning as the working electrode (WE). The electrochemical system is connected to a stepper motor a and a multichannel potentiostat device b . Additionally, a syringe pump system c is connected via an inlet to the cell. This configuration allows for precise delivery of the desired electrolyte formulation, as well as enabling accurate positioning over the targeted measurement area on the WE substrate and the deposition of a single droplet of electrolyte. Upon contact of all three electrodes, the system is ready to execute the selected protocols (Fig. , Section Setup).
