Abstract

Controlling ion transport in nanofluidics is crucial for various applications. This paper introduces a neuro-inspired energy harvesting method using confined van der Waals crystals to maximize ion diffusion flux and generate electromotive force. A robust nanochannel, similar to neuron cells, enables steady-state ion diffusion for extended periods, exhibiting high ion selectivity (95.8%), energy conversion efficiency (41.4%), and power density (5.26 W/m²). This design strategy opens possibilities for large-scale passive power generation.
