The vibrational strong coupling between the vacuum field of the resonator and the molecular oscillators can be utilized for the modulation of physicochemical properties of molecules even under dark conditions. In this study, we focused on the dynamics of water molecules to control ionic conduction. The proton conductivity was found to increase up to 10-fold, and ion migration was modulated with dynamic hydration.
