Ion‐selective organic electrochemical junction transistors (IS‐OEJTs) were prepared and their performance was studied for the detection of potassium, calcium, and silver ions. In this kind of sensors the conducting polymer poly(3,4‐ethylenedioxythiophene) (PEDOT) doped with poly(styrene sulfonate) (PSS), PEDOT : PSS, is utilized for transduction of chemical information to electronic information in the solid state. In order to achieve selectivity, the channel region of the transistors was coated with ionophore‐based polymeric membranes.
