“…47,48,50,57,58 On the other hand, the water-evaporation phenomenon that converts ambient thermal energy into electricity via water−solid interfaces has also aroused broad attention recently in which streaming potential may also act as an important contributor. 3,59 The representative examples and the corresponding underlying mechanisms, materials, solution, and output performance are summarized in Table 1. Besides, we also mark the relevant information of representative research groups.…”

“…Among them, the streaming potential is of primary importance for hydrovoltaic generators that convert waste mechanical energy into electricity because the form of motion required by the streaming potential is more diverse. On the one hand, Guo et al extended the streaming potential to twisting, dropping, and waving potentials combined with nanostructured materials. ,,,, On the other hand, the water-evaporation phenomenon that converts ambient thermal energy into electricity via water–solid interfaces has also aroused broad attention recently in which streaming potential may also act as an important contributor. , The representative examples and the corresponding underlying mechanisms, materials, solution, and output performance are summarized in Table . Besides, we also mark the relevant information of representative research groups.…”

“…Especially large values of dimensionless pressure differences can be expected in capillarity-driven electrokinetic phenomena, in particular, in systems with side evaporation from thin (nano)porous films (see Figure 4 for the schematic). A simple model for the distribution of hydrostatic pressure in such systems has recently been developed in ref ( 10 ) using the Darcy law for the description of viscous flow along the film and assuming a constant evaporation rate (controlled by the external mass transfer) from the fully wet part of the film. Under these assumptions, one obtains a linearly decreasing hydrostatic-pressure gradient along the film (in contrast to the constant pressure gradient occurring in the pressure-driven mode), which is because ever more liquid is lost to evaporation while moving along the film.…”

“…As discussed in ref ( 10 ), the tangential hydraulic flow is driven by the gradient of (negative) capillary pressure arising beneath the curved menisci at the external film surface. While moving along the film away from the immersed end, ever larger negative pressures are required to drive the viscous flow along the ever longer film segment.…”
