ionovoltaic device that generates electric energy by the ad/desorption
of ions on a solid–liquid interface, as water droplets move
on a solid surface, has a unique operation mechanism. Here, we describe
the relationship between the output voltage/current and resistivity
of a monoelectrode. This relationship plays a key role in device operation
by demonstrating a simple, robust, and paintable carbon-composite-based
ionovoltaic device beyond the limitations of the conventional rigid
ionovoltaic devices. The results
of this work show the output voltage/current is linearly proportional
to the output voltage in a specific resistivity range (10 Ω·cm
< ρ < 5000 Ω·cm).
