1 Introduction Stimuli-responsive supramolecular materials are crucial in the design of advanced functional systems as they can reversibly modulate both structural and functional properties in response to external stimuli [1-4]. Such adaptive materials provide unique opportunities to integrate controllable molecular organization with bioinspired functionality as many biological assemblies are regulated by reversible redox signals and energy-driven processes.

A novel pump-free miniaturized reverse electrodialysis (RED) system was designed to provide lasting power transduced from salinity gradients. Named solid salt RED (ssRED), this quasi-battery uses solid salt instead of electrolyte solution for streamlined usage. It is portable, flexible, comparable in size to a universal serial bus flash drive, and is easily activated from a small amount of water.
