Abstract
As extensive researches on renewable energy are emerging, sensory devices increasingly need appropriate power sources that supply not excessive but sufficient electricity at low cost in eco-friendly manner. Reverse electrodialysis (RED) is a promising candidate to produce electricity from the salinity difference between sea and river water. Opposite transport of ions across ion selective membrane between the aqueous solutions flowing alternatively generates electric power. Recently, research on RED has expanded not only to enhance power density but also to enable integration with other energy generation systems. The state-of-the-art of RED is compact and readily disposed. Importantly, miniaturized RED has evolved to electrodeless circuit and power patch that can be customized at will. By highlighting emerging applications of RED, this talk will focus on the introduction of recently developed miniaturized patch-type RED which can be used to power various devices. We emphasize the potential of this RED for sensors and look forward to its wide range of application scopes in the future.
