Energy-conversion devices that generate electric energy from the movement of water have been actively studied. In case where ions play a major role in driving such devices, a clear causal relationship including the effect of ions on the operation of the device has not been clarified. Though, it is assumed that the electric signals generated when the devices are driven by a flowing water droplet or squeezed droplets are associated with the potential profile across the solid-liquid interface, the understanding of the cause and effect is unclear. The unclear understanding of the principle is a critical bottle neck for the enhancement of device performance and device application, such as ion type and concentration sensor. In this study, we investigated the correlation between the contact-area-dependent electric energy generated by ion dynamics and the electric potential across a solid-liquid interface. Further, the dependencies of the operational conditions of the device on output performance were faithfully investigated and the potential for a novel ion type or concentration sensor was introduced.

固液界面上离子吸附引起的接触面积相关电能的特性分析

已经积极地研究了从水的运动中产生电能的能量转换装置。在离子在驱动此类设备中起主要作用的情况下,尚未弄清包括离子对设备操作的影响在内的明确因果关系。尽管假定当设备由流动的水滴或挤压的水滴驱动时产生的电信号与跨固-液界面的电势曲线相关联,但对因果关系的理解尚不清楚。对原理的不清楚理解是增强设备性能和设备应用(例如离子类型和浓度传感器)的关键瓶颈。在这项研究中,我们研究了由离子动力学产生的与接触面积有关的电能与跨固液界面的电位之间的相关性。此外,忠实地研究了设备的操作条件对输出性能的依赖性,并介绍了新型离子类型或浓度传感器的潜力。
