We verified the origin of water-infiltration-induced electricity generation by an ionovoltaic effect, specifically, ion–surface interaction induced potential asymmetry in porous structures. When 20 μl of water (NaCl, 0.1 M) infiltrates into a porous CuO nanowire film, electrical power of ∼0.45 V and ∼0.23 μA is produced for 40 minutes. Moreover, a method of proportionally amplifying electricity is presented, and the practicability is shown by turning on an LED with infiltration of eight seawater droplets.

多孔CuO纳米线薄膜中的离子伏效应识别水渗透诱导的电能

我们通过离子伏特效应，特别是离子-表面相互作用在多孔结构中引起的电位不对称，验证了水渗透诱导的发电的起源。当20μl水（NaCl，0.1 M）渗入多孔CuO纳米线膜中时，在40分钟内产生约0.45 V和约0.23μA的电功率。此外，提出了一种按比例放大电流的方法，并通过打开具有八个海水滴入的LED来显示实用性。
