Effective wetting area between liquid and solid plays an important role on the energy transport at the solid-liquid interface, while it has not been described in the existing theoretical models and its direct measurement is still unable and challenging. In our previous study, we demonstrated that the quantitative effective wetting area depends on the surface wettability for the liquid layer on the nano/microstructured surfaces using the electrochemical impedance measurement. However, due to the sensitivity of the measurement system, the solid-liquid contact area of a single fine droplet at the structured surface is still open for questions. Therefore, we propose a novel chip-based device of miniaturization electrochemical impedance system to estimate the effective wetting area of a single fine droplet at the structured surface.
