Abstract The evaporation‐induced hydrovoltaic effect represents a promising avenue for green energy harvesting and self‐powered ion sensing. However, the intricacies of designing solid‐liquid interface insufficient systematic research on influence parameters performance hinder advancement high‐performance devices. Herein, governing principles nanochannel size, material conductivity, surface properties, water evaporation based multidimensional regulation nanochannels by dip‐coating carbonization processes are systematically elucidated. Guided obtained mechanisms, flexible sensing device with photothermal conversion capability is prepared, exhibiting an open‐circuit voltage exceeding 3.5 V wide univalent range 10 −7 –10 −1 m . Ultimately, fabricated successfully serves electrolyte monitoring. These results elucidate correlation between controllable design solid–liquid interfaces (on structure, environmental factors) devices, paving way practical applications.
