Cover Story: Stable reference potentials are essential for reliable potentiometric measurements, yet conventional liquid-filled electrodes struggle to meet the demands of miniaturized and portable systems due to leakage, instability, and maintenance demands. Solid-state and membrane-based reference electrodes address these limitations by eliminating the liquid junction while maintaining potential stability. This review summarizes recent advances in polymer and composite reference membranes, highlighting material strategies based on ionic liquids, conducting polymers, lipophilic salts, and carbon nanomaterials. The article illustrates how these innovations enable compact, flexible, and low-cost potentiometric platforms for innovative sensing technologies. View this paper
