We propose a 1-dimensional (1D) nanofluidic energy conversion device by implementing a surfacepatterned Nafion membrane for the direct energy conversion of the pressure to electrical power. By implementing a 200-nm-thick nano-bridge with a 5-nm pore size between two microfluidic channels, we acquired an effective streaming potential of 307 mV and output power of 94 pW with 0.1 mM KCl under pressure difference of 45 MPa. The experimental results show both the effects of applied pressure differences and buffer concentrations on the effective streaming potential, and are consistent with the analytical prediction.
