Recently, various energy transducers driven by the relative motion of solids and liquids have been demonstrated. However, in relation to the energy transducer, a proper understanding of the dynamic behavior of ions remains unclear. Here, we demonstrate a method by which to generate continuous electrical energy with the flow of a water droplet through an electrolyte-insulator-semiconductor (EIS) structure. The output power and energy conversion efficiency of the transducer are 29.8 %. Also, we propose and verify a hypothesis pertaining to the ion-dynamic operation mechanism of the transducer as “Ionovoltaic phenomena“, which holds that the electron flow is induced by the adsorption and desorption of ions. Further, we describe ion specificity and bio-fuctionality, an important characteristic of electrical signals generated by various water motion, which is determined by the characteristics of microscopic ion properties. |
