An Empirical Model of Ion‐Selective Organic Electrochemical Transistors (Adv. Mater. Technol. 2/2026)

Ion-Selective Organic Electrochemical Transistors In their Research Article (10.1002/admt.202501217) Mainul Hossain, Yasser Khan, and co-workers present an empirical model for ion-selective organic electrochemical transistors (IS-OECTs) that predicts sensitivity and selectivity across varying ion concentrations in biofluids such as sweat. The model captures steady-state behavior in the presence of both target and interfering ions and accurately reproduces concentration-dependent responses, demonstrating strong reliability for advanced electrochemical sensing.
